What words are engraved on the hat to show temperament?

Makes people look deep.

Temperament refers to people's relatively stable personality characteristics and style tolerance. Refers to the calm and generous style of poetry. Psychology believes that temperament is a typical and stable dynamic feature of psychological activities independent of the purpose and content of human activities. Temperament is human nature, and there is no difference between good and bad. It only paints a certain color on people's words and deeds, but it does not determine people's social value, nor does it directly have the significance of social moral evaluation. A person's liveliness and steadiness cannot determine the direction of his life. People of any temperament type can be virtuous and beneficial to society, and can also be morally corrupt and harmful to society.
