————— from Song Yu's "Gao Tang Fu": The concubine is in the sun of Wushan, the obstruction of the high hills, Dan is the morning clouds, the twilight is the rain, the morning is the twilight, under the balcony.
- Legend has it that Emperor Yan had many children, and one of them had a daughter who is very famous in the history of literature, and that is Yao Ji. It is said that Yao Ji is very young and beautiful, but unfortunately she died too early when she reached the age of marriage. Her soul flew to Mount Yaoji and turned into a Yao grass, this Yao grass has extraordinary magical powers, and whoever eats her fruit can be loved by the opposite sex.
- Emperor Yan took pity on Yaoji's untimely death, so he sent her to Wushan to be the local god of clouds and rain. In the morning, it turned into a cloud and mist, and it swirled in the mountains, and at dusk it turned into a drizzle, carrying mourning. This is called "morning clouds and twilight rain".
——Before the Warring States Period, King Chu Huai once traveled to Yunmengze, stayed in the palace of the Tang Dynasty, and dreamed that the god of clouds and rain in Wushan came to pour out his love. Later, King Huai was unforgettable, so he built a temple called "Chaoyun" for Yaoji. Later, King Huai's son, King Chu Xiang, also dreamed of a goddess coming to meet in Gaotang, so he asked Song Yu to make "Gao Tang Fu" and "Goddess Fu"!
