Bad goods have a long history and can be regarded as an old brand in Chinese cuisine. Eating bad is a legacy of the pre-Qin period, which was first recorded in the Songs of the South more than 2,000 years ago. After the Southern Song Dynasty, eating bad food was prevalent, and Lin 'an, the capital, sold bad abalone, bad sheep's hoof, bad crab and bad pig's head meat. By the Yuan, Ming and Qing Dynasties, it had developed into home-made, except for the bad products in the market. In A Dream of Red Mansions written by Cao Xueqin in the Qing Dynasty, the delicate and bad tastes such as bad goose web and bad quail were mentioned, and Yuan Mei also recorded the homemade bad meat, bad chicken and bad quail in Suiyuan Food List.
