The so-called size is relative, the big one can be infinite, and the small one can be infinitely small, which is inexhaustible.
It seems that the problem is not "big" or "small", but "what kind of big" and "how to change from small to big" or "how to change from big to small". The question remains: Why is it "big"? Why "small"?
The great river east is magnificent, and the small bridge is gentle and meaningful. The big one and the small one have their own advantages and uses.
It is very important to see the big from the small, and to see the big from the small. The two complement each other, set off each other and complement each other.
