In the Qing Dynasty, the local soup dumplings in Yangzhou became more famous. In the poet Lin Lanchi's "Three Hundred Songs of the River", there was a poem describing "pouring hot dumplings", which was preceded by a small preface: "In the Spring and Autumn Period and the East, the broth was easily condensed and poured into Luo fine noodles, thinking that it was steamed buns. When steamed, the soup melts without leaking, and Yangzhou tea houses are good at it. " His poem says: "It's hard to swallow and easy to taste. A round and round one is the best to hide, and it's not necessary to be humble when it's strong outside, but to guard against hand-probing when it's hot." Xiaolongbao has been passed down since then and has been widely welcomed by diners.
