Shocked? It was because when they said alcohol I thought about either the US or the UK. China had never crossed my mind. In China, alcohol was made by two legendary persons named Yi Di and Du Kang who belonged to the Xia Dynasty. This period was about 2000 BC—1600 BC. Research says that in ancient China, beer with 4% alcoholic content was widely drunk by people.
