First, big things are hard to bear. When you encounter a big and difficult thing, it depends on whether you can face it bravely, avoid it, and take it bravely.

Second, look at the mentality in good times. When you encounter adversity or prosperity, it depends on your mind, whether you are open-minded enough and whether you can afford it.

Third, look at self-restraint when you are angry. When you encounter a happy thing or an irritating thing, in other words, you have both gains and losses, happiness is gain, and anger is loss. Look at your self-restraint and see if you can bear the burden of humiliation.

Fourth, the group stops seeing and knows. By yes, I mean whether to stay or not. When it comes to staying or not, it depends on your knowledge and whether you can make a correct judgment. If you should go, you should stay.

When it comes to personnel difficulties, it depends on responsibility; When it comes to wealth, it depends on the mind; When it comes to joy and anger, it depends on self-restraint; When it comes to groups, it depends on knowledge. These four viewpoints are actually a thorough understanding and grasp of life and society. These are all at a higher ideological level, so they are called philosophical health preservation.
