My Mother spent her early life in Catholic Convent Schools during the War with Japan in Shanghai; she came from a rich family with very long family history; hence I'd always linked Shanghai with richness. Until I had chances to be encountered with some bad experiences: one classmate, man from Shanghai, he stoled my notebook and cheeted on the exam. Later, at the brink of the time when China had just opened their iron door, my housemate subletted a room to a family of three who're from Shanghai; the kid had very bad behavior, the snobish wife never being polite... her hi-pitch voice totally annoying. Not an easy family to deal with, at all.
All the nostalgia turned to very sour.
