In prison, Chen Qizi developed lice on his head which made him itched intolerably. After being tortured by the prison wardens with bamboo planks, Chen Qizi discovered that the bamboo planks would be split into strips; he then packed these wooden strips together to create the original fine-toothed comb to clean his hair away from lice  and dirt. Foundation of Comb trade. According to a legend, after the defeat of Chiyou, the craftsman Hao Lian, who knew how to make combs, was captured, imprisoned and given the death sentence. The prison warden, Huang Fu, discovered that Hao Lian could make combs and advised him to make a comb to save his life overnight. The comb made by Hao Lian was presented to the Queen Luo Zu, but Hao Lian was already executed before an amnesty could be issued. After Hao Lian's death, Emperor Xuan Yuan appointed Huang Fu to lead other craftsmen in comb-making  based on the models left behind by Hao Lian.
