↑ Classic of Mountains and Seas, "Beyond the Seas - East"; quote: "雨師妾在其北，其為人黑，兩手各操一蛇，左耳有青蛇，右耳有赤蛇。一曰在十日北，為人黑身人面，各操一龜。" translation: "The Rain Master's Concubine is to the north of [the Fusang tree (扶桑) and the Hot-Water Dale (湯谷)]; her body is black, each of her two hands holds a snake; on her left ear is a green snake, and on her right ear a red snake. Another says that to the north of the ten suns, there is a black-bodied, human-faced person, whose each [hand] holds a turtle."
