Zhuge Liang's "Commandment Book" originally said: A gentleman's trip is quiet to cultivate his morality and frugality to cultivate his morality. If you don't stay in the park, you won't have a clear ambition, and if you don't be quiet, you won't be far away. If you study quietly, you must learn. If you don't study, you can't learn widely. If you don't have ambition, you can't succeed. You can't be energetic if you are slow, and you can't cure sex if you are dangerous. Years go with the times, meaning goes with the days, and then they become withered, and they don't meet the world, and they are sad to stay in the poor house. What will happen?
