How did the white deer milk skin stem come from?

White deer milk skin stems come from two sources:

1. From the slogan shouted by fans when they picked up the plane. White Deer is an actress and model in Chinese mainland. The real name is Bai, so fans shouted "the natural beauty of white milk skin" when they picked up the plane.

2. Run. In the fourth issue of the sixth season, the punished white deer must shout three times: "Bai Mengyan with milk skin, Bai Mengyan with peerless beauty, and Bai Mengyan with fairy descent".
