Merchants cards are ok, and there are many kinds, especially girls, and there are many outlets outside the four major banks. The service is ok, but without a password, I may be a little unaccustomed.
Traffic, construction is good, traffic has Liu Xiangka, see if you like it.
The most distinctive card is the WOW card of Shanghai Pudong Development Bank, which looks very distinctive and can be viewed online. But if it is not recommended in Shanghai, there are few outlets.
Just follow the three items I said above, and it's almost there.
