I know a good one in Chongqing. I looked it up online and went to school to have a look. I thought their hot pot master explained it well, so I signed up there directly. Now I have time to try it in the fish-hole shop. It tastes really overbearing. The school is called Chongqing Zhongke Vocational School, which is located at the bus hub station of Hongqi Hegou in Jiangbei.
