China is the hometown of soybean, with more than 6,000 years of cultivation history and 2,000 years of processing history.

Xuzhou is one of Kyushu. As early as 4,000 years ago, in the era of Emperor Yao, there was a big Guo Peng here. The founding monarch was Peng Zu, who is said to have lived for more than 800 years. He is regarded as the originator of cooking by chefs in past dynasties and the most sacred teacher of China's food culture. Many Taoist health preserving classics still retain Peng Zu's health preserving heritage. In contrast, archaeologists were very surprised to find well-preserved soybeans in the storage room of Guishan Han Tomb in northern Xuzhou. Interestingly, it was in Peng Zu's hometown that the well-known enterprise Weiwei Group was born.
