The previous two sites have established the dependence of everyday order on invisible labor: memory, coordination, and backfilling keep shared life continuous, and judging change requires seeing on whom this labor falls. Mobility is the first form of precisely such a set of changes, and what it rewrites first is the location and the bearers of the support network.
Mobility is often written as a straight line from the old place to new opportunity. One leaves constraint behind and enters a larger city, a more suitable job, or freer relationships, and spatial movement thereby becomes equivalent to an increase in possibility. Another narrative writes migration as the beginning of the dissolution of community, as if trust, family, and the nearby must necessarily vanish once people no longer remain in place. Both narratives grasp part of the truth, and both easily obscure what migration actually changes. What moves is not only bodies and addresses, but also the paths of seeking help, the clock of care, the visibility of each other's lives, the eligibility to enter new relations, and whether old commitments can continue to be honored across distance. Migration can enlarge the subject's options; it also reorganizes the support network — and gains and costs often fall on different people.
Consider a fictional family. Lin Lan lives with her mother and younger brother in the Qiaonan neighborhood. Before leaving to work in another city, she was responsible for booking her mother's follow-up appointments, occasionally looked after the neighbors' children, and received help from the familiar repair shop and the community canteen. After her departure her income rises, she escapes the gender bias of her former workplace, and for the first time she can arrange her life independently. At the same time, her mother's appointments pass to her brother, the vacancy in the neighbors' occasional childcare has no fixed taker, and Lin Lan must maintain her participation through nighttime calls.
This scenario is not an empirical survey. It uses longitudinal change to ask: which ties actually carried tasks before the migration; which tasks were interrupted, transferred, or reinvented during it; and what the old and new networks respectively provide afterward — and what they demand. Only by unfolding the timeline can we avoid writing those who stay as pure victims, and avoid treating the leaver's freedom as an individual achievement without conditions of support.
Movement, Departure, and the Original Network
Lin Lan's departure from her address did not mean an immediate disconnection from her family. She could still remit money, make appointments, call, and return home on weekends. What distance changed were the conditions of these actions: what had once been done casually now required devices, overlapping time, relayed information, and transportation costs. Some ties weaken with distance, while others become clearer. When they lived together, her mother's needs were often handled quietly by Lin Lan, and the family took the results as things that happened naturally in the course of daily life; after her departure, tasks had to be named and assigned before her brother could see the existing division of labor. Rupture can also occur without migration. People living in the same stairwell do not know each other's names; requests in a cohabiting household go long unanswered; spatial proximity does not automatically produce the nearby. Conversely, distant members can continue to participate through stable commitments and reliable handovers. Chapter 1 understood the "nearby" as relations in which problems can be received, passed on, and responded to. Migration changes the nearby because the original paths of response are no longer reachable at the same speed and in the same manner — not because kilometers as such carry moral significance. Lin Lan cannot arrive immediately when her mother falls, but she can keep the medical records, contact community personnel, and bear part of the cost. Her brother can arrive, yet may not know the long-term medication. The neighbors know the rhythm of the household's life but have no right to view medical information. Each node holds only partial capability.
If the family still assumes that Lin Lan "understands these things best," all requests will first be sent to her, and she will then have to search remotely for someone on the scene. She becomes a relay point of the relationship network: her body has left, but the coordinating labor has not. The network appears to be maintained, while fragility concentrates. Treating distance as rupture ignores this ongoing labor; treating the existence of communication as the completeness of the relationship ignores which actions cannot be completed remotely. Reliable judgment requires listing concrete responses rather than summarizing all relations with "we keep in touch" or "we have drifted apart."
Qiaonan was not only warmth. Acquaintances asked about Lin Lan's marriage prospects and interpreted her refusals to help without pay as ingratitude; her former workplace allocated opportunities by seniority and connections, and she could hardly change her position. Migration released her from continuous evaluation, allowed her to find more suitable work, and brought friends with whom she could learn together. A critique of the costs of mobility that presupposes the old community as good would require the pressured to preserve, by staying, an order familiar to others. Family, neighborhood, and local tradition can provide support — and can demand obedience in exchange for that support. Leaving is sometimes not the failure of a relationship but a necessary act by which the subject restores her boundaries. Nor are new relations merely a downgraded substitute for old ones. In the new city Lin Lan built mutual aid with colleagues: someone delivered medicine when she was ill, and someone shared experience in a rental dispute. These ties are weak at first, yet they can become reliable through repeated response. A community can be built, not only inherited.
When Lin Lan returned home, relatives kept enumerating the work others had taken on since her departure, finally concluding that she ought to give up the new position. The added burdens are real material, but they cannot automatically decide who must go back. Whether the prior division of labor was fair, whether other members have the capacity to take on tasks, and why public services are absent — each of these requires separate judgment. "We took care of you in the past" can also be inflated into an open-ended debt. Relations do involve reciprocity and commitment, but the object, degree, and duration of repayment cannot be interpreted solely by the party providing the help. If every departure is defined as betrayal, support becomes collateral restricting migration. Those who leave may also use personal freedom to erase commitments. If she explicitly promised to bear a certain cost or complete a handover and then, upon gaining a new opportunity, stopped responding, she cannot simply say that everyone should be responsible for themselves. The boundaries of the subject protect choice, and at the same time leave the limited commitments personally undertaken open to questioning. Freedom and responsibility need not cancel each other. The better questions are: which responsibilities arise from explicit commitments, which from capacity and urgent need, and which merely from the inertia of old roles; whether the manner of fulfillment can change, whether alternative bearers exist, and who decides the cost of exit.
If we looked only at what help Lin Lan received, we would think Qiaonan a complete safety net. In fact the network is open to different people to different degrees. Those familiar with the dialect, those who own housing, and those with long-standing reputations find it easier to obtain responses, while new tenants, people living alone, or those whose habits differ from the mainstream may remain at the margins. The reliability of the old network also often depends on a few people filling gaps. Auntie Chen at the community canteen remembers who has difficulty moving; Uncle Zhou next door keeps the spare key; Lin Lan handled the online appointments. When people say "neighbors help each other," what is actually happening is that a few intermediaries connect scattered relations. When migration removes one of them, how far the network declines depends on whether knowledge is shared, whether roles are replaceable, and whether commitments have boundaries. If all contacts exist only in personal phones, what departure causes is not abstract nostalgia but concrete handover failure. Her brother, though he has not moved, also sees his relational position changed by shift changes at work, friends leaving, and adjusted public-service windows. Sorting people into "the mobile" and "the fixed" easily overlooks that staying also requires continuous adaptation. Changes in the mother's physical capacity shrink the relations in which she can participate. She used to help others pick up their children, and therefore people were willing to accompany her to medical visits; this reciprocity is not instantaneous exchange, but it has a history. After Lin Lan's departure, even if she only purchases services on one occasion, historical ties may still come into play in exceptional moments.
But this does not justify making past contribution the sole qualification for receiving care. Those who have never had the capacity to help others also have basic needs. Reciprocity can explain how relations form; it cannot by itself decide who is worth rescuing. In describing the impact of migration, one must at minimum observe the leaver, those who stay, the intermediaries of the original network, and the relations at the destination. Recording only the migrants' income or satisfaction cannot show others' added labor; recording only the hometown's losses cannot see the leaver's release from constraint and the capacity generated by new networks.
The New Place and the Maintenance Labor of Distance
After arriving in the new city, Lin Lan needed to understand rental rules, transit lines, hospital entrances, and the informal customs of the workplace. Public information answers some questions; many judgments rely on colleagues' reminders and repeated trial and error. "The city has more opportunities" is a description of the number of options, not a claim that every option is reachable. Entry requires deposits, documents, time, language, and social trust. A person may in principle be able to use many services, yet if she does not know the entrance or cannot bear the consequences of error, the opportunities remain in the catalog. In Qiaonan she possessed a reputation formed through long observation; in the new city, reliability must be rebuilt. Past capabilities are not necessarily recognized by new institutions, and familiar ways of seeking help may be seen as overstepping. The cost of entry is not a personal failure of openness but the fact that relations require shared time. When an established member misses a meeting, others understand it through long records; when Lin Lan misses one, she may be taken as lacking responsibility. The same behavior entering different relational histories carries different interpreted consequences. Acquaintance judgment carries the risk of favoritism, and formal procedures can protect newcomers. Clear contracts, appeals, and service standards reduce the degree to which she must please intermediaries. When criticizing institutionalized services, one should not treat private familiarity as the only answer.
Formal entrances may still assume that users already possess local knowledge. A complaint form, for example, requires an internal reference number; a service window opens only during working hours; the newly relocated need someone to explain. Institutions applying the same rules to everyone can still make entry costs highly uneven. Residents of the receiving place also bear change. A growing population may tighten housing, schools, and public space, and may also bring services, tax revenue, care, and new social ties. One cannot attribute all conflict to migrants, nor refuse to discuss capacity and distribution in the name of openness.
Lin Lan calls her mother every evening; it seems to take only twenty minutes. Before the call she must wait for her brother to send the test results; after it she contacts the hospital; if her mother is feeling low, her own rest plan for the day changes. Relational time cannot be measured by call duration alone. Long-distance coordination also demands temporal synchronization. When Lin Lan gets off work, her mother is already preparing for bed; her brother's rotating shifts prevent three-way discussion. Everyone has free time, but there is no jointly available window. Frequent contact may still fail to complete decisions. Asynchronous messages offer convenience: medical records can be forwarded, questions answered later. They also keep unfinished matters continuously present in everyone's attention. Seeing a message without being able to handle it immediately may produce both a sense of participation and a sense of suspension. Greetings appear daily in the family group chat, yet the mother's actual follow-up visits are still completed by the brother taking leave. Digital visibility easily leads members to believe they are continuously participating. Judging what is borne must return to tasks, consequences, and replacement costs. Conversely, transferring money with few calls cannot be directly judged as indifference. Lin Lan may bear costs according to a family agreement, with emotional expression taking other forms. The quality of a relation cannot be uniformly scored by one visible behavior. Platform reminders can reduce forgetting, but they cannot decide who should take over. If a system automatically pushes tasks to whoever most often responds, it consolidates the existing division of labor. The "fastest handler" in technical records may simply be the person least able to refuse.
The next chapter will compare convenience services with mutual aid in detail. This chapter keeps only one boundary: communication and transaction tools can reduce some of the costs of distance, but one cannot infer from this that relational responsibility has been taken over by technology.
After Lin Lan left, her brother took on more hospital accompaniment, Auntie Chen took on more occasional inquiries, and Lin Lan took on remote coordination and remittances. The family did not lose all support; costs were redistributed across the nodes. Transfers often occur through small acts, without a single formal decision. The brother lives near the hospital, so he goes first; Lin Lan knows the system, so she books again; Auntie Chen happens to be downstairs, so she looks in. After repetition, incidental help becomes default duty. Default is not always illegitimate. In emergencies, the nearest and most capable acting first can reduce harm. The questions are when temporary assumption becomes visible, whether it can be handed over, and what happens when the bearer refuses once. Lin Lan's new work creates higher income, part of which goes to the family — a real shared gain. If her brother frequently misses work for accompaniments and his professional opportunities shrink, the distribution of the family's total gain cannot be read from remittance amounts alone. This structure can be exploited by organizations. Employers require employees to relocate across cities while treating family care, housing transitions, and the rebuilding of relationships as private matters. The institution gains deployable labor; the work of maintaining the continuity of life is absorbed by families and communities. Pointing this out does not mean every transfer involves an intent to exploit. Organizations may underestimate consequences, and employees may choose actively. Judgment requires looking at decision rights, gains, compensation, alternative paths, and exit consequences — not inferring malice directly from the existence of costs.
More worthy of vigilance is the institutional move of interpreting an inability to migrate as a deficiency of capability under the slogan that "talent should be flexible." Those bearing care duties, those with bodily constraints, and those lacking start-up capital disappear from the distribution of opportunities. Mobility turns from one condition among others into a total evaluation of worth.
The family says Lin Lan owes her hometown; Lin Lan says she has borne the most for years. Both sides can list facts, and both may select the favorable ledger. What is given in a relation spans time and kinds and can hardly be converted into a single balance. That it cannot be quantified does not mean it cannot be discussed. One can specify separately the money, the time, the on-site action, the holding of emotion, and the opportunities given up, and determine which were voluntary gifts, which explicit commitments, and which took shape under unequal pressure. If a master ledger decides who is entitled to leave, whoever does the calculation will hold the subject's freedom. If all accounts are refused, patterns in which a few bear the load long-term can never enter public language. The aim of multidimensional recording is not to price kinship but to make transfers visible again. Lin Lan realizes her brother's burden has grown and is willing to adjust the arrangement. Moderate guilt can signal that a commitment has fallen through and prompt a person to respond to the relation. Emotion should not be regarded wholesale as external manipulation. When every choice of a new life triggers the same accusation, and no action can complete the repayment, guilt loses its concrete object. What it demands is the restoration of a role, not the resolution of a problem. At that point one must ask: which loss is to be remedied, what action counts as completion, and who else should also change. Those who leave may likewise label every criticism emotional blackmail and thereby exempt themselves from explanation. A critique of relational power still must allow the other side to raise concrete consequences. The key difference lies in whether the demand is limited, answerable, and connected to actual responsibility.
This two-directional scrutiny keeps both freedom and community from becoming closed slogans. Freedom that refuses to acknowledge its conditions of support leaves the costs to those with fewer options; a community that refuses to acknowledge the right of exit turns support into possession.
Judgment Across Time and Support for Continuity
Asked in the first month after her migration, Lin Lan might be excited and lonely at once; a year later, new relations have stabilized and old ties have been re-divided; if her work is interrupted, the original network may again become a fallback. A single interview or income comparison cannot carry all this change. This family setup is used only to compare the transfer of care work. The outcomes of real migration are shaped by region, migration type, class, gender, and time scale; without corresponding research or records, one cannot infer from this chapter that migration generally weakens family or social networks. Longitudinal material should record at least the pre-migration network, interruptions during transition, entry at the destination, maintenance of old ties, activation in crisis, and possible return. It must also distinguish subjective feeling, actual behavior, and institutional conditions. Feeling supported does not necessarily mean receiving action when needed; a decline in contact frequency may also reflect healthier boundaries. A rise in total family income does not show that every member benefits; completed care does not show that its bearing is sustainable; the migrant's satisfaction does not show that resource distribution at the destination is free of strain. Average indicators suit limited questions and cannot replace relational paths. Conversely, listing every cost may also obscure the long-term capacities migration creates. Lin Lan's new skills, friends, and income will enlarge the whole family's options years later. Critique must not automatically read short-term fluctuation as net loss.
What must be compared is not only migrating versus not migrating, but which realistic alternatives exist: whether work in place is available, whether care can be supported by public services, whether remote arrangements are feasible, how high the cost of return is. Nonexistent ideal options cannot be used to reproach real choices. Material must ultimately serve revisable judgment. If new relations stabilize, old tasks have reliable takers, and members can renegotiate, early judgments of rupture should be lowered; if all maintenance depends on one person's excessive backfilling, surface contact should not be taken as completed recovery.
With migration alike, decision positions may differ completely. Lin Lan actively accepted a job; another neighbor may have been forced to move out by rising rent; a corporate manager chooses a cross-city post, while a temporary worker changes dwelling with the project and cannot refuse. "One can always leave" is actual freedom only when alternative paths are reachable. Deposits, qualifications, care duties, identity procedures, and information can all raise switching costs. A formally open road does not show that everyone possesses equal capacity for mobility. Staying in place may likewise not be a stable choice but the absorption of adaptation after others move. Schools face student turnover, community organizations rebuild contacts, family members take over tasks. The speed of the mobile differs from the speed at which local relations form, and the latter often never enters the project plan. Organizations want workers to migrate with demand, yet may restrict their cross-department records, benefit continuity, or options upon leaving. They praise geographic flexibility while preserving institutional dependence. The old community, in turn, may forbid departure yet refuse actual support when a person loses work. From this one cannot conclude that "discourses of mobility are all deception." Migration can indeed bring autonomy and creation. The object of critique is the selective definition: demanding that subjects move when it favors the institution, and be self-reliant when continuity requires the institution to bear its share.
A more hidden inference treats support networks as consumable resources. Decision-makers assume families will always care, neighbors will always fill gaps, newcomers can always integrate on their own — so handover and public services can be cut. The more resilient the relations, the more likely they are to hide costs on behalf of institutions. Exposing this inference is not teaching how to exhaust networks, but bringing the fillers of gaps, the attrition, and the interruptions into evaluation. If the capacity for support is continuously drawn on without recovery, it may no longer exist at the next crisis.
Before migration, the tasks Lin Lan bore can be made explicit: which require on-site action, which can be done remotely, who holds the information, and which situations require escalation. A handover cannot demand that she institutionalize all her private relations, but key services should not exist only in personal memory. During migration, a transition period needs to be set. When the brother takes over appointments he can obtain the records and explanations; Lin Lan's new employer allows her to handle the necessary procedures; the community knows the emergency contact has changed. Transition is not the indefinite extension of old roles but time for a new division of labor to take shape. After migration, commitments should be open to renegotiation. Income, shifts, bodies, and relations all change; one arrangement cannot be fixed forever. Review does not imply that past commitments were false; it acknowledges that responsibility needs the support of real capacity. If Lin Lan returns to Qiaonan years later, she may bring new capacities, or she may return because work has gone badly. Writing return only as failure forces a person to sustain unsustainable choices; romanticizing return as homecoming erases the life she built elsewhere. Returners likewise need to re-enter. The old neighborhood has changed, the family has formed a new division of labor, and one cannot assume the original roles will be restored as they were. Continuity preserves history; beginning anew acknowledges that both the subject and the environment have changed.
Institutions can support portability: key records travel with the person; benefits and qualifications are not excessively bound to a single organization; public services spare family ties from carrying all continuity. These arrangements still must handle privacy, resources, and responsibility, and cannot rely on technical connection alone. Repair at the relational level includes explicit response. The leaver states what she can bear; those staying state the added burdens; both allow certain expectations to end, and allow new forms to earn trust gradually. Not every relation must be preserved; being able to end with boundaries is also a capacity of the subject. If Lin Lan loses her job in the new city, her former employer may say she should not have taken the risk, recruiters may say she lacks adaptability, and her family may read the outcome as proof that leaving itself was wrong. Inflating one setback into a judgment of the subject strips the migration choice, after the fact, of the conditions that made it reasonable at the time. Outcomes of course must enter review. She may have underestimated housing costs; the organization may have concealed the term of the post; the economic environment may have changed. Separating these factors is the only way to know whether next time should improve information, safeguards, personal planning, or institutional responsibility. Success stories carry selection bias of their own. Those who manage to stay and build networks are the most visible; those who return early, switch frequently, or rely on family support disappear from the typical narrative. Using a few successes to prove that everyone should be mobile disguises conditions of support as personal courage.
A reliable migration regime should permit trial, error, and return, without letting one transition determine lifelong qualification. Portable records, transition support, and the absence of excessive penalty for gaps can make mobility a revisable action rather than an identity that must be proven by continuous success. This applies equally to those who stay. Not migrating does not indicate a lack of enterprise; it may be the choice that follows care commitments, local creation, or realistic costs. If a community can sustain itself only by degrading leavers, and a discourse of mobility can expand only by degrading stayers, both are substituting identity evaluation for judgment of conditions.
Migration exposes a mass of coordinating acts, and markets and platforms accordingly promise to replace the trouble with services: appointment handling, instant delivery, remote accompaniment, automatic reminders. These can indeed lower particular costs and spare people from depending on exclusionary acquaintance networks. But completing transactions and sharing burdens are not the same relation. A service can deliver on order, yet need not recognize why a task recurs, who bears the exceptions, or whether the user retains another entrance after failure. The next chapter will discuss in detail why convenience cannot by itself replace mutual aid. Judging the consequences of migration requires separate inspection: whether the departure is autonomous, whether conditions of entry are reachable, how old commitments are handed over, how new relations form, who bears long-distance maintenance, and which alternative paths exist in crisis. No single indicator can make the overall judgment in their stead. Mobility need not be celebrated as automatic liberation, nor mourned as inevitable disintegration. The freedom Lin Lan gained is real; the labor her brother added is real; the support formed by new friends is real; and the fragility of the old neighborhood after losing its intermediaries is real. The task of critique is not to choose where the subject lives, but to prevent any one party from writing its own gains as everyone's progress and others' backfilling as the natural background.
When the costs of connection can be seen, migration can preserve both the right to leave and the responsibility of relationship. A person can leave an oppressive position, can enter a new shared life, and can make limited, completable responses to the commitments she still wishes to keep. The strength of a community lies not in fixing people in place, but in this: after members move, support can still be handed over, rebuilt, and, when necessary, ended with boundaries.
