The lower body writing, also known as the lower body poetry movement, is a avant-garde poetry school initiated by poets such as Shen Haobo and Yin Lichuan. As the name implies, it emphasizes "body" in its writing, opens the door of the body and releases the power of life. Of course, it can also be simply said. If a famous saying is used to explain this genre, it is "thinking with the lower body". So in these poems, you can easily see many things that can't be broadcast. Anyway, it's just a little tacky. Personally, I feel very bad I don't like this kind of modern poetry very much, so I think he is a very bad modern poet.
The above is my personal opinion, I hope it will help you.
