In 1926, Mr. Jiang Dingfa sold the dumplings at the Chenghuang Temple in Ningbo, and unveiled the century-long history of the cylinders. Jiang Dingfa painted the homonym "Cylinder Duck Dog" of the nickname "Jiang A Dog" on the plaque. Since then, an old-fashioned Yuyuan brand has been established. After centuries of tempering, the craftsmanship has been passed down from generation to generation, and the deliciousness has always been the same. The craftsmanship of Ningbo Tangyuan has become the intangible cultural heritage of Zhejiang Province, Chinese famous snacks, and Chinese gold medal tourist snacks. A dog's Ningbo dumplings are white and round, with black and white, soft and smooth taste, sweet and not greasy, and delicious.

In Ningbo, there is a well-known sweets and dim sum shop, which created Jiang Dingfa, Xiaoming Jiang Agou, originally a city slum. In 1926, he set up a booth at the entrance of the old temple of Ningbo, in order to operate the wine garden, bean garden and jujube soup. Sweet dessert. In the early days of the War of Resistance Against Japanese Aggression, he opened a new store in Kaiming Street. Since I am not literate, when I ask people to write a sign to discuss the name of the store, I will use my own name as a homonym. I will draw a water tank, a duck, and a yellow dog on the signboard. The strange signboards are very interesting, and all ages are well-known. The popularity of the songs is very wide, which leads to customers' wealth and prosperity. At the same time, he also highly stresses the quality of sweet foods. It is now sold in public, so that it is white, quality, soup, beautiful, sweet, and put a bowl of sugar on the business counter, which can be added by customers. Therefore, the business is getting more and more prosperous. Before the liberation, the working people who often visited the "cylinder duck dog" had a tribute to the store: "Pulp board garden cylinder duck dog, eating a bowl is not enough, then eating a bowl of money is not enough, take off the clothes and hold Head." Explain that the characteristics of the snacks and management provided by the tank ducks at that time were adapted to the consumption level of the working masses at that time and the taste of the public, and were well received by the general public.
