People's spirit, like bowstring, can't always be tense. We should also relax properly after work. The so-called "one relaxation is the way of writing and martial arts", that's what it says. Long term intense work will make people's spirit appear abnormal, become turbulent, and generate negative emotions such as worry, fear and anxiety. On the contrary, after work, go to the temple to attend collective worship, so that the spirit can be relaxed, and every day will be refreshed. So it's important to learn to relax.
