在离乡迁徙和参与市场经济过程中，都市打工者寄居于“家”与“社会”这一重组的社会空间之中。在日常关于“家”、“家乡”和“职业生涯”的记忆中，人情以及人际间的物质流动起着重要的媒介作用。与此同时，物质媒介本身引入了新的“记忆”/“遗忘”的可能性。记忆在这一系列通过媒介的交流过程中加强了不确定性，甚至变得难以表述。这一难以表述的不确定性可以促成人际间的人情记忆和认可，同时也激发了对“遗忘”人情的担忧以及对陌生“社会”的道德批评。记忆并非只是根据“现在”的“社会”语境来进行建构，而是将不确定性引入对“现在”和“社会”的理解。

In the context of migration and participation in a market economy, migrant workers live in the restructured social realm between “family” and “society”. In the memory of “family”, “hometown” and “career”, interpersonal relationships and material entanglements play an important role of media. Meanwhile, the material media also introduce new possibility of “memory” and “forgetting”. Memory in such communication becomes uncertain and even inexpressible. This inexpressible uncertainty opens up a space for the memory and acknowledgement of interpersonal relationships, worry about the “forgetting” of interpersonal relationships and moral critique of unfamiliar “society”. Memory is not constructed in the social context at present but introduces uncertainty into our understanding of the “present” and the “society”.
