She is a mute girl who has lived in Sike Mountain with her master for a long time and has no involvement in worldly affairs.
There is snow every year in Sike Mountain. When she was nine years old, a mysterious boy riding a carriage came to her side. Snow flakes stuck to the young man's eyebrows. He gently took the broom from her hand, his eyes like stars: "Junior sister, let me help you sweep. I will be your senior brother from now on, and my name is Shao Wushu."
The time in Sikeshan became colorful because of him. He liked to take her to the wild woods to collect pine branches and teach her how to catch hares. He often smiled, but did not reveal his true feelings to her.
Occasionally, she would see him sitting lonely in the moonlight, singing songs that she had never heard before, singing and crying for a long time. He had a world that she could not step into.
Time flies, both of them have grown up, and he finally leaves Sike Mountain. It snowed again, and he left without saying goodbye, leaving only the same ruts left in front of the door.
There will no longer be a young boy who takes the broom from her hand with a smile.
After her master died, she finally took all her courage and set foot on the beautiful world that belonged to him.
