The life wisdom left by Laozi can be summarized in four words: the weak survive. If you are weak, you will exist. Survival is strong, and extinction is death. If you die like this, you are weak. This is Lao Tzu's consistent thought. Lao Tzu said, what is the weakest thing in the world? Water. What is the most invincible? Water. Look, the fire is so fierce that water can put it out! This stone is so hard that water can destroy it! Water droplets have worn away the stones, and the flood has come, leaving nothing behind. Therefore, the softest in the world is the strongest in the world. So I repeatedly said that you should be soft, weak, low-key, lean back and don't rush forward.

The book Laozi runs through the survival wisdom of the weak from beginning to end. Not only that, Lao Tzu also pointed out how to be flexible for us. The first is pretending, the second is forbearance, and the third is letting. When we read Laozi's books, we will find that he likes to use a word called "if". For example, if he is straightforward and clumsy, then he will develop into an idiom in China. What does it mean if? I think so. The straightest seems to be curved, the smartest seems to be stupid, the smartest seems to be the most confused, and the most beautiful seems to be the ugliest.
