Presently the Commanderies of Liang, Han, Pa, Shu, Wu-Iing, Ch’ang-sha, and Lu-chiang are all inhabited by Marn. They eat rice gruel mixed with the flesh of various fish, they pound on containers and howl to honor P’an-hu with sacrifices. This
custom has lasted until the present day. The above are the reasons for our saying:
“Bare buttocks, yellow trousers do
Reveal descendants of P’an-hu.”
