The invention of hats originated from people's important understanding of power and status in ancient China society. In the slave society, hats were widely used only in the bureaucratic ruling class at first, and their decorative and symbolic functions symbolized the ruling power and aristocratic status. At this time, the hat should be called "crown" and "crown". Only emperors and ministers of civil and military affairs can wear them. Different styles of hats show their status and power. In the late Qing Dynasty, the introduction of western culture and hat culture made "hat" popular in society. In modern society, "hat" can be said to be developing in the opposite direction of history. It is no longer a symbol of status and power, but has become an ornament and a tool for heatstroke prevention and cold protection.

The arithmetic difference between numbers is 1cm, forming a series.
