The general meaning is: it was windy and cloudy last night, and it was supposed to be a storm, but unexpectedly this morning the sky was clear again. Compared with the natural world, the human heart is hard to shake, and it is not as easy to change as the weather. Maybe so. Some people's hearts can always be swayed by interests, but there are also some people's hearts that are difficult to shake. In other words, people's hearts are much more "stubborn" than the weather. A heart that has gone astray may not be able to come back no matter how hard it is pulled; a cold-blooded heart may not be warmed by thousands of fires... Some people who persevere with all their heart are very admirable, such as integrity and kindness. ; But some persistence violates the principles of life, such as being selfish, climbing on the shoulders of others, and persisting to the end. What a terrible thing. Therefore, if the human heart can choose to be conservative and change, that is a smart behavior.
