In ancient times, coquettish actually refers to two books: The Book of Songs (because the best chapter of the Book of Songs is "national style", which can be represented by wind) and Li Sao.
Later, coquettish became synonymous with learning, and "literati" can also be called "poet". If someone likes to show off his knowledge, call him "coquettish".
Later (probably in the Ming and Qing Dynasties), coquettish changed from describing literati to describing women. When a woman is called easy virtue, she is called coquettish. Women show off their beauty, which is also called "coquettish".
Sao:
1. Style refers to the national style in the Book of Songs, and Sao refers to Qu Yuan's Li Sao, which was later generally called literature: Tang Zongsong Zu, slightly coquettish.
2. Become a leader in the literary world or lead in some way: lead.
3. Refers to the frivolous behavior of women: coquettish.
Charm means charm and interest.
