Who is the sleeping god in China?

Chen Tuan, according to records, living in a stone room "every sleeping place can't stand more than 100 days", which is called "the best sleeping technique in the world".

Chen Tuan once wrote a song "To the Forbidden City", which said: "I love sleeping, I love sleeping, I don't lie on the carpet, I don't cover myself, I have a flaky pillow, and I will return to the ground with hemp fiber. Shocked the ghosts and gods, the old minister snored and slept. Close your heart to think about Sean, think about Fan Li, talk about Meng De, and stop talking about Liu Bei, two or three gentlemen, and strive for some leisure. It's like a minister unfolding his eyebrows, unbuttoning his navel and sleeping on the top of a green hill and among white clouds. I don't care if the jade rabbit rises in the east and the red wheel sets in the west. "
