United States, City of Cambridge, Areston Community.
This community is very close to both MIT and Harvard University, with a quiet environment, good schools, and its own park.
However, Zhang Xinwen chose to live here because, compared to other middle-class residential areas in Cambridge or Boston, the housing prices here are lower, and the living conditions are not bad, making it quite cost-effective.
Moreover, many of the residents in the community are staff from MIT and Harvard, which adds a sense of security.
There's no denying that although being a university professor in the United States carries a certain social status, it does not belong to the high-income group, especially when you're not very famous yet.
It's well known that this country really takes "birds of a feather flock together" to the extreme.
Middle-class and poor communities are mixed together, with knowledge and crime often just a street apart. Everyone seems to be used to these things.
