Beppu: Nothing makes people feel depressed and out of their wits like parting. Therefore, although the mood of parting is the same, the specific situation is different. Although there is no exact reason for the separation between the two sides, there must be sadness when there is separation, which will inevitably fill people's hearts, make them lose their will and bear great psychological and spiritual pain and shock. Who can describe the moment of separation and express the feeling of being inseparable forever!

The snake catcher said: snakes are highly toxic and can cure diseases. Snakes can be caught at the cost of rent and the risk of death. I want to help him restore taxes, but he won't. Crying and telling me: poisonous snakes are not as good as tax poison. Embarrassed neighborhood, too much tax. The deceased was a relative, with ten rooms and nine vacant rooms. Officials disturb the people every day, and the people are in danger every day. Why don't I catch snakes? Only twice a year. The more I listen to it, the more sad it becomes. I wrote an article, hoping it will be useful for people who observe people's feelings.

Yueyang Tower: In the fourth year of Qing Dynasty, my friend was demoted as a satrap. Let me write an article about rebuilding Yueyang Tower. The feeling of "touching guests and poets" changes with the change of scenery. It's sad when the weather is cloudy. The weather is sunny and I am in a good mood. In ancient times, however, benevolent people were different. They worried about the world first and enjoyed it later. Alas, without these people, who would I be with? (Expressed the author's political ambition and attitude towards life)

Zuiweng Pavilion: Chuzhou is surrounded by mountains. Langya Mountain is the most beautiful, with a drunken pavilion on it. The pavilion was named Taishou. There are different scenery and endless fun in the mountains in spring, summer, autumn and winter. People come and go from Chuzhou. At the satrap banquet, people laughed and laughed, and the satrap was drunk. In the evening, people gradually leave, and the mountain forest becomes a paradise for birds. Birds know the joy of mountains, but people don't know the joy of traveling with the satrap. People don't know that the satrap has something to be happy about.
