"Tao" is a commonly used Chinese character, pronounced "Tao", which was first seen in Oracle Bone Inscriptions in Shang Dynasty. "Tao" consists of "water" and "longevity", and its original meaning refers to big waves; There are sounds such as waves in the extended meaning.

The word Tao is an earlier word than "wave" and "wave", which should be the original word of wave, and later refers to big waves, especially those in the sea.

At the beginning of Daozi, the word "longevity" was simplified from water. To understand this word, the key point is to understand the meaning of this short message. Jane's life, the reverse S-shaped line in the middle belongs to Yang, indicating an infinite time line, the words in the left and right corners in turn indicate the time period, and the words in the left and right corners indicate that time passes one stage and then goes to another. In a person's life, it is equivalent to living one jiazi and entering another jiazi, so the word longevity means longevity.

In the concept of representing waves, the lip words on one side correspond to a curve, indicating the peak, and the lip words on the other side correspond to another curve, indicating the trough. Therefore, simply using the word "longevity" of the pen has the meaning of waves, which is the principle that the word "Tao" can represent waves.

The word longevity is mainly developed in the sense of longevity, so the glyph of the old man is added, and some words are added below to indicate the meaning of life cycle. So the so-called Tao refers to the shape characteristics of waves, which is similar to the meaning of the word wave. Pottery in Shang dynasty may be the common name of waves. In Shang dynasty, the word Tao may also refer to a long river, but it doesn't come and go.

Dedicating the word Tao to the huge waves is the evolution of future generations. The longevity of the simple pen has the shape of waves, plus the shape of an old man, who is fierce, so the word longevity contains great wave meaning, so Tao refers to huge waves. The huge waves of the sea are usually accompanied by the sound of waves, so the word Tao can also be extended to refer to the sound of waves.
