They are sold in supermarkets and grocery stores in vegetable markets. In Chongqing, it is a bit difficult for you to see the bottom material of hot pot. Other places are hard to say.

I recommend the bridgehead card. It is delicious. Summer and autumn are also good, but a little salty.

Yesterday, the supermarket downstairs was on sale. I bought five packages of Qiaotou brand hot pot bottom materials in one breath. It's really cool ~ Haha ~ 3.3 yuan only bought one bag after the discount ~
