In the fourth year of Jiajing in the Ming Dynasty (A.D. 1525), Xie Zhao was recruited as Xu by the Lotus Princess of the Ming Dynasty. He went back to his hometown to visit relatives. After playing bamboo in the mountains, he tasted the local beef and was immediately attracted by its delicious taste. He thought it was more delicious than the delicacies in the palace, so he wanted to stay longer. When Emperor Jiajing learned about it, he built a tucheng around Qinghua Town, which was divided into five levels: North Gate, South Gate, West Gate, Northeast Gate, Southeast Gate, North Gate, South Gate, Xiguan, Southeast Gate and Northeast Gate. The Lotus Princess House was also built for the princess to live in. She often sits in the car and eats beef.

In Pok Oi, in the past, it was generally only in autumn, winter and early spring that the small car beef was produced and sold, mainly because the soup of braised pork in summer could not be solidified and should not be stored. When sold at parties, the processed beef will be bundled in trolleys and put on the market. Don't shout, someone will buy a catty or two around, or a steamed bread will be rolled up to eat, or two side dishes will be shared with relatives and friends at home.
