People's bodies are soft when they are alive, but they become stiff after death. Vegetation grows soft and fragile, but becomes hard and withered after death. So strong things belong to the category of death, and weak things belong to the category of growth. Therefore, striving to be brave will be destroyed, and trees that are strong will be cut down. The strong are always in the lower position, and the weak are in the upper position.

Laozi has a profound insight into society and life. He believes that everything in the world is a kind of death, and all the weak are a kind of life. Therefore, Lao Tzu believes that in life, we should not try to be brave and win, but be humble and have a good attitude towards life. We think this chapter once again expresses Laozi's dialectical thought. This idea comes from the observation and summary of natural and social phenomena. Here, whether it is the weak or the strong, whether it is the "living" or the "dead", it is the internal factor of the development of things. This conclusion also implies that strong things have lost their vitality, while weak things are full of vitality. The ideas expressed by Laozi in this chapter are extremely wise. He vividly tells people about natural and social phenomena, and hopes that people will not show their own prominence everywhere, but always strive for strength and competitiveness. In fact, in real life, there are many such people, and such examples are endless. Of course, this is also in line with Laozi's consistent ideological proposition.

It is Lao Tzu's consistent practice to expound profound philosophy with natural phenomena. I was born weak and stiff when I died. Plants grow weak and wither after death; Therefore, strong things are short-lived, and weak things are crucial. Therefore, when the army is strong, it will be destroyed. Strong trees are broken, strong trees are downhill, and weak trees are rising.

Therefore, Lao Tzu advised people: in this world, don't try to be brave and win, be humble and have a good attitude towards life.

Laozi's theory of "softness" not only has a great influence on the politics, commerce, war, the outside world and life of the Chinese nation for thousands of years, but also is an important magic weapon for self-cultivation.

Medicine believes that flexibility is one of the important physical qualities. Flexibility exercise can make the human body in a relaxed and soft state, make the whole body circulate essence and qi, smooth qi and blood, balance yin and yang, and improve the physiological gasification function of the human body. Maintain good flexibility, live an agile life, rarely suffer from motor system diseases, such as shoulder, knee, thigh and leg pain, which can enhance human immunity and resistance.

When Carnegie, a famous American scholar, introduced the secrets of health care to people, he asked people to imagine themselves as soft as old socks. He said, "Make your body as soft as old socks. I always put an old chestnut sock on my desk and put it there to remind me how soft it should be. "

The theory of "nurturing softness" requires people to make their bodies soft, fresh, smart and full of vitality in a loose and quiet state, just like the mountains, streams and grass on the shore. The softer, more flexible and more energetic your body is, the greater your life energy will be, and you will live a long and healthy life.
