Who saved Shen Miao from missing on Jade Rabbit Festival?

On the Jade Rabbit Festival, Xie Jingxing rescued the kidnapped Shen Miao, and the two lived alone.

The man swam to Shen Miao's side, grabbed her and swam to the surface. In this ice and snow, the lake is bitterly cold, and it is still difficult to swim alone, but he swims easily with a person. Swimming to the original boat, I lifted Shen Miao and threw it on the pass, turning over myself. In the twilight, Shen Miao saw that it was Xie Jingxing who saved her.
