In August, I spent more than RMB 1 1,000 in a cottage cafe in Minhang District. Recently, I received the phone number 02 157932007, saying it was Jinshan District.

Interesting. You believe this, too? The telephone numbers of Shanghai's public, security, bureau, business and other units are generally numbers starting with 02 1-2 * * * * * * * * *. At first glance, your phone number is a civil or company phone number, or a virtual number made by number changing software.
