Fuso had no name originally. She was just a spirit attached to the Fuso tree. She had been quietly in that deserted place for thousands of years. It was not until someone cut down the Fuso tree she was attached to to make a wooden comb that she really left there.
However, she was not very lucky. Her owner was betrayed and died. Poor Fusang was thrown on the grass. When she was lamenting that she had to live on a grassland, the man who seemed to be shrouded in the moonlight discovered her and took her back to a thatched house at the foot of Shu Mountain. He gave her the name of Fusang.
Fusang knew that his name was Li Luo, and that there was a fox beside him named Bai Sheng, but she didn't know why there was a bright red mark on Li Luo's forehead, and she didn't know why Bai Sheng was always worried about Li Luo going out, because they would go down the mountain every six months, and Bai Sheng was the most nervous at that time, and she didn't know why the bearded Taoist priest on Shu Mountain always looked thoughtful when he saw her. . . .
