Explain why Laozi thinks that the combination of "water" and "goodness as water" represents the highest wisdom and virtue of the Chinese nation.

"Good hydropower" is the general program of Laozi's philosophy of multi-power and multi-power, and the combination of zero power and multi-power is also the embodiment of Laozi's outlook on life. The noblest virtue should be like water: water has the selfless virtue of nourishing the growth of all things, and it can give benefits to all things without competing with them, so it is closest to the so-called Tao. Indeed, as a natural resource, water plays a self-evident role in the world. Without water, there is no life. It is with the nourishment of water that plants and animals can grow and reproduce, and the world becomes vibrant and colorful. As an important energy source, water also facilitates the colorful life of human beings in the form of hydropower generation; Water is also dotted with colorful world with ever-changing attitude, or flying springs, streams, lakes or the sea, giving human beings beautiful enjoyment. It can be said that water has made great contributions to human society, but it flows to a lower place in obscurity, content with humble status and has the virtue of modesty.
