Look at the following introduction: "Chuanchuanxiang", also called "Mala Tang", is actually another form of hot pot, so people often call it a small hot pot.

At that time, Chongqing hot pot had just entered Chengdu catering market, and some unemployed people in cities and towns set up stalls near some bustling places such as shopping malls, theaters and video halls to make a living.
