"It's fun to fight with heaven and people." The complete sentence is "it's fun to fight with the sky; Fighting the ground is fun; Fighting with people is fun. " This sentence comes from 19 17 "Struggle for Self-improvement", which expresses the author's indomitable and optimistic revolutionary spirit in the face of difficulties.

"Struggle with the day, fun! Fighting the ground is fun! It's fun to fight with people! " It is the concrete embodiment of this philosophical thought. Only by working together with heaven, earth and people can we follow the objective laws of nature, advance in harmony with nature, and realize the true meaning of struggle and endless happiness. It seems that there is a meaning of conforming to nature and respecting the laws of nature, and it is by no means a perverted idea that it is fun to oppose heaven and earth after tampering.
