"History of rites and music in Han Dynasty" wrote: "It is better to retire and build a net than to be a fisherman in the forest." This means that people just stand by and watch the fat fish in the river and appreciate it in vain. They will never get the fish. Might as well go home and make a net to catch it.

This idiom tells us that if we want to make our motherland prosperous and the people live a happy life, we must work hard and struggle hard. Clearly speaking can only make our country wrong, and hard work can make our country rich and strong.

Only with a net bag can you taste the delicious fish. No matter what happens in the world, if it is just a fantasy divorced from reality, or if there is just no rhetoric and empty talk about down-to-earth work, it is like standing by the river, sighing at the fish and achieving nothing. On the contrary, if you work hard, even if the practice fails, you can still learn a lesson and get closer to "success".
