What does Wang Xiaobo mean by "living in black humor, you won't feel humor"?

"Black humor" is a kind of self-mockery of the heavy and miserable life. Just like in "Golden Age", Wang Er always needs to close his door because of low back pain, and because the pillow in the infirmary has barbs, his lower back is like being hit by a shotgun, just like being hit by Pig Bajie. This kind of narrative will make us smile, but the parties themselves feel only pain. Yes, the word black humor itself determines the nature of life pain, and you certainly won't feel humorous when you live in it.
