Ask the difference between black humor, gray humor and cold humor. Thank you.

Black humor is different from ordinary humor. Its absurdity, cynicism and cynicism contain heaviness and anguish, tears and pain, melancholy and cruelty, so its wry smile contains tears and even anger. Later, people usually used the word "black humor" in this sense. Cold humor is a little black humor, but it is different from black humor. It can be understood as humor without obvious intention. When the parties tell a cold humor, they don't deliberately achieve the humorous effect. It's a very casual humor. It's up to you to laugh or not. "Cold humor" is a kind of faint humor that is naturally revealed inadvertently. It is the humor that makes people dumbfounded, puzzled, thoughtful, epiphany and laugh, and it is the humor that makes people memorable. It is called "cold humor" because it is not only humorous, but also "cold". It means to make people laugh and think. Usually jokes based on the dark side of things. What is humor and what is gray humor? The dictionary is full of related entries, which are too dry to understand. An example from the news is very telling. It is said that in Shanghai, there was a man who was extremely tired of the world and jumped into Suzhou River with the determination to die. When the police arrived, they tried to convince me, but it was useless. I must die. After smoking a cigarette, the dead man changed his mind and climbed up by himself! The person next to him asked, Hey, why are you still alive? Answer: The river stinks unbearable. I really want to die! This is gray humor. What a joke: you are ready to die, and you are still afraid of the smelly water? But if this matter is put in the environmental protection bureau, it will not be a joke: it can only show that the pollution is too serious!
