According to legend, during the Qianlong period of the Qing Dynasty, there was a farmer named Tang in Hefeng County, and his son was eighteen years old. A family of three made a living by farming. This hardworking old couple has a unique skill in pasta. In their spare time, they make cakes in the market and earn a small amount of money and clothes. A few years later, the old man was old, and his son married his daughter-in-law, who was very filial. He passed on the bread skills his father-in-law gave him. And every morning, I will personally make cakes of various flavors and serve them on the table for breakfast. My parents-in-law praised me, and my family of four was happy every day. People in the neighboring village are envious of this family.
Later, Emperor Qianlong came here incognito and heard that there was such a family. So I came here and tasted the cakes made by this clever and filial daughter-in-law with wheat flour, millet and seasoning. At that time, she was very surprised and ordered the chef to come here to learn this craft. Since then, I have enjoyed this cake with ministers at the meeting of monarch and minister at the end of each year. Later generations called this kind of cake Tang 18 in-laws cake to show their admiration. Also known as "filial piety cake", the 18th in-laws cake in the Tang Dynasty, which has been passed down to this day, fully demonstrates the cooking skills and wisdom of our ancestors, and fully embodies the long history of Chinese food culture and the filial piety of Chinese children to their parents.
