String string is a special snack that strings fresh food with a stick and then cooks it in a pot with secret soup. 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 skewers various dishes with bamboo sticks and puts them in a hot pot to rinse and eat. "Chuanchuanxiang" originated in the mid-1980s. In order to make a living, some unemployed people in Chengdu set up stalls near some busy places, such as shopping malls, theaters and video halls.
