Geographically, Beicai Town belongs to the suburb of Shanghai. The urban area of Shanghai refers to the former old city, that is, the top ten districts before the county was changed, while Beicai belongs to the former Chuansha County and merged into Pudong New Area after 1995, so this is still the concept of suburbs. Judging from the current prosperity, Beicai can completely belong to the urban area, but stubborn Shanghainese have their own established concepts, so it is still the concept of suburbs.
