Sijimei Tangbao restaurant was founded in 1922, and its owner, Tian Yushan, was born in Hanyang. Tian Yushan is an observant businessman. He started his business as a snack. When he opened the door, he saw that there were many gold names and cloth shops in houhualou and Jiaotong road of Hankou, and the operators were mostly from Jiangsu and Zhejiang provinces. Therefore, he opened a Xiajiang flavor snack shop named "sijimei Tangbao restaurant", and invited master Xu Daguan from Nanjing to make Xiaolong soup dumplings.
