If a person were born in the beginning, the rainbow should have seven colors.
If people were in the beginning, mountains and rivers should depend on each other.
If people were born in the beginning, they would never be separated from each other.
If a person had done so at the beginning, he would have never given up.
It's just that people will never be the same as before, and the first time will not last forever. Should we look back or look up? It's ultimately difficult, just do it and see.
