Foreigners think it's funny that China people say this sentence. Is it impossible for heaven and man to be as high as the sky?

This sentence may be a humorous homonym, which contains some joke elements of China culture. In China culture, there is a school called Confucianism, and there is a famous saying called "the harmony between man and nature", which means that man and the universe are one. This thought holds that man should live in harmony with nature and pursue unity with the universe.

So the sentence "The sky is so high and so high, can't it be unified?" It can be interpreted as a kind of ridicule, that is, in China culture, people often express their understanding and ridicule of this idea in a humorous way. Of course, there are great cultural differences between humor and jokes, so some jokes may be difficult for people with different cultural backgrounds to understand.

Generally speaking, this sentence is a manifestation of cultural differences. If foreigners find it ridiculous, it may be because they don't know or are not familiar with this idea in China culture.
