Why do people in China have two or three names?

The possible names after the two words can already express the meaning of the name.

For example:

Three words can be separated by one word, or they can imply the generation of the family.

For example, my family name is "the founding of the country sets the world", so it's my father's turn to say that the middle word here is "Tian".

Or take a word apart to express some meaning: Wang. It's Li, so we can guess that this person's parents must be surnamed Li.

China's culture has lasted for five thousand years, so the name is naturally much more complicated than that of foreign countries.
