Interpretation: The existence of opposition and its cyclic transformation in the opposite direction are the laws and characteristics of the movement of Tao, and weakness is the exertion and performance of the role of Tao.

Everything in the world comes from the concrete "existence" of matter, and "existence?" It also comes from the abstract and intangible "nothing" (Tao).

The former sentence is "the movement against the Tao". Everything has its opposites, and the relationship between them is mutual transformation and cycle. As a simple dialectical thought of Laozi, he believes that everything in the world is in the process of constant movement and change, and is transforming into its own opposite.

? But "the weak use Tao" has profound philosophical significance: everything has its own morphological characteristics. Newborn children, buds emerging from the ground, represent vitality and vitality; The flowing water in the mountain stream is strange, and when it gathers into the sea, it is choppy; Because of the elasticity of water, the function of Tao is incomparable. Therefore, there is a saying that the weak is stronger than the strong, and the desire is stronger.

Is there a Tao in the last sentence? Everything is born, everything in the world is born out of nothing, and finally the whole world is born, just like the goddess of the pot in ancient mythology made men and women out of clay, and finally human beings continue to thrive and change the world.
