What does it mean to sit and watch the sky?
Idiom moral:
The frog in the well thinks that the sky he sees is all the sky. He doesn't believe that there is such a vast ocean in the world. Frogs have never walked out of that well, just as some people have never walked out of their original living environment and have narrow doubts about the world they have never seen. Nature is great and infinite, in contrast, the individual is so small. There are so many things in nature that we don't know. Only by observing nature deeply can people increase their knowledge and turn the unknown into the known. People should break through the shackles that bind them and bravely go outside. Only by trying to contact the new world that I have never seen before can I enrich my life and sublimate my personality.
