What is the origin of steamed soup packets in Kaifeng?

Soup dumplings originated in Tokyo (now Kaifeng), the capital of China in the Northern Song Dynasty. According to "Tokyo Dream", it was called "Plum Blossom Steamed Bun in Wanglou Mountain Cave" at that time, which was called the first in Beijing. The steamed buns on the first floor were created by Huang Jishan, a famous master of steamed buns in Kaifeng. Huang Jishan, whose name is Huang Fatty, is from Huang Jiaying Village, hua county City, Henan Province. Forced by life, 13 years old, he began to escape from famine, begging in Kaifeng, and went to a steamed bun shop as an apprentice. After starting his career, he met Zhou Xiaode, a famous chef in Kaifeng at that time. 1922, Huang Jishan hired him as a chef with high salary and opened a restaurant. At that time, they mainly engaged in glutinous rice balls, and their business was very prosperous. Mr. Wu, who lives near the restaurant, is a calligrapher. He often goes to restaurants to eat steamed stuffed buns, and he is full of praise every time he eats them. Once, Huang Jishan asked Mr. Wu to give the restaurant a name. Mr. Wu picked up a pen and wrote the five characters "Chuxin Restaurant" on a piece of propaganda paper, meaning the first one in Beijing, which became their font name. In 1950s, Mr. Cao, Huang Jishan's apprentice, personally made steamed buns for the party and the country.
