Context: "Xiaolongbao" originated in Changzhou, Jiangsu province, by Wan Hua Tea House in the years of Daoguang Emperor (1820 to 1850). Xiaolongbao evolved from the guantangbao (soup-filled dumplings/buns) from Kaifeng, Henan province, the capital city of Northern Song Dynasty (AD 960–1127).

There are numerous styles of xiaolongbao in Jiangsu cuisine. Shanghai-style xiaolongbao originated in Nanxiang, which was a neighboring village of Shanghai in Jiangsu that eventually ended up becoming an outer suburb of Shanghai's Jiading District. The inventor of xiaolongbao sold them in his first store in Nanxiang next to the town's notable park, Guyi Garden. From there the xiaolongbao expanded into downtown Shanghai and outward. The Suzhou and Wuxi styles are larger (sometimes twice as large as a Nanxiang-style soup dumpling) and have sweeter fillings. The Nanjing style is smaller with an almost translucent skin and less meat.
