The first paragraph can be said from the perspective of career. As the old saying goes, too much is too late. After the flowers bloom, it is time to wither. You have to know how to rush back, keep the best things in mind, and then leave. Because, if you indulge in your own achievements, what awaits you will be failure.
In the second paragraph, from the perspective of friendship, friends should also keep an appropriate distance. When you rely too much on your friends, your friendship may break down and your feelings may deteriorate. Distance is also a beauty. Friends should also share yours and mine, so that they can have endless aftertaste.
The third paragraph is obviously about love. Another poem by Li Ao is "Love is pure happiness", which means that love doesn't believe in tears. If you feel pain, it is love that made a mistake. So, this poem is the same. When two people get along for a long time, it is inevitable that some problems will occur, and of course there will be pain. Once the pain happens, it is not love. It may be extreme, but I think that's what Li Ao is trying to say. Because we know that now Li Ao has his own wife and son. However, he still lives alone in the house in Yangmingshan. I only go to spend the weekend with my wife and son. Because there will be a generation gap with my son and wife, and there will be friction together.
He is an eccentric, so the theme of this poem is abnormal. Usually people think that deep feelings should stick together every day, and a good career should go up a storey still higher. And he emphasized "distance".
I was in a hurry, so I didn't arrange it. In fact, you can read Li Ao's other articles and his other poems first. If there is not enough time, look at his quotations. How much can we know about him? A poem is difficult to understand through analysis.
