Li Hao, an Englishman, engaged in hand knitting for his wife, which led to his research on knitting machinery. 1589, William Li Faming introduced the world's first hand knitting machine to knit woolen trousers. 1598, Li Hao was transformed into a knitting machine that can produce fine stockings, thus completely changing the history of hand-made socks.
