This kind of food is called chuanchuanxiang. Chuanchuanxiang, which originated in Chengdu, Sichuan, is not only one of the traditional snacks in Sichuan, but also the most popular embodiment of grassroots cuisine. Chuanchuanxiang is actually another form of hot pot, so people often call it a small hot pot. The origin of the name "Chuanchuanxiang" is because it is a snack that uses bamboo sticks to string various dishes together and put them in a hot pot to rinse and eat. It can be said that as long as there are people, there is a string of incense, and even to a certain extent, string of incense has become one of the representatives of Sichuan style.
