There are hibiscus in the east and Ruomu in the west. Fusang is in the east pole and wood is in the west pole. In myths and legends, Fusang and Ruomu should have been different names for a sacred tree. "Shuo Wen You Bu": "Nie, at the beginning of the day, went out to Tanggu, Toyo, Dengbosang, and Nie Mu Ye." Duan Yucai's note: "When the cloud: Nie Mu, Bo Mulberry Leaves, first came out of Tanggu, the East." Nie is an archaic word. Yuan Ke's Notes on Shan Hai Jing and Ye Bei Jing: "In this case, Shuowen says that the east pole is like a tree, and Benjing and Hainei Jing say that the west pole is like a tree, so it can't be the same." Because the "Fusang" in the East China Sea and the "Ruomu" in the West Pole were originally sacred trees for the sun to inhabit, but they have different names where the sun rises and sets.
If the wood is shining, it should be the brilliance from the wood, representing brilliance.
