Excuse me, how to distinguish some cold jokes from brain teasers and jokes?

Cold jokes are those that sound very cold. For example, the narrator is calm and steady, and the content that deviates from normal logic is even boring. After listening, people are dumbfounded, and the aftertaste makes people laugh. Generally give the answer directly.

A sharp turn in the brain is the pleasure of deviation between normal thinking and results. What is important is the disparity between thinking process and results.

A joke is that the speaker's expression, language, movements and tone are very pleasant, and the content comes out without thinking, which directly produces a funny effect.
