According to some versions of the Pan Gu legend, his tears flowed to make rivers and radiance of his eyes turned into thunder and lighting. When he was happy the sun shone, but when he was angry black clouds gathered in the sky. One version of the legend has it that the fleas and lice on his body became the ancestors of mankind. The Pan Gu story has become firmly fixed in Chinese tradition. Nevertheless, it is rather a latecomer to the catalog of Chinese legends.
Some opinions hold that it originated in south China or southeast Asia.
There are several versions of the Pan Gu story. Among the Miao, Yao, Li and other nationalities of south China, a legend concerns Pan Gu the ancestor of all mankind, with a man s body and a dog s head. Among the gods there was great enmity between King Gao Xin and his rival King Fang. The dog Pan Gu overheard what was said, and when Gao Xin was sleeping, slipped out of the palace and ran to King Fang. The latter was glad to see him standing there wagging his tail.
