Nanxiang Shantou is a well-known traditional snack in Shanghai. Shantou is a southerner's statement, the northerners are called buns, Shanghai people prefer to call "Nanxiang Xiaolong", Nanxiang Shantou store is a century-old store, opened for more than 100 years a specialty thin stuffing, a bag of braised and famous Yang Sifang. The queue in front of the store is the famous "landscape" in Yuyuan, and there are so many people waiting to buy at any time and anywhere throughout the year, which has become a "live advertisement" for "Nanxiang Xiaolong" without money. Nanxiang Xiaolong has many varieties, such as fresh meat Xiaolong, wild vegetable Xiaolong, mushroom Xiaolong, etc., but the most famous is the crab powder Xiaolong. There is a swipe of crabs in the store. I heard that two or three hundred pounds of hairy crabs are to be dismantled every day. Seeing the master crabs, it has become one of the tourists' viewing projects.
