The earrings are also called earrings. They were originally called dāng. In the ancient Chinese Eastern Han Dynasty, liúxī “shìmíng” said
chuān ěr shī zhū yuē dāng ，xìng yú mán yí ，shèng yú huá xià 。Chinese: 穿耳施珠约珰，兴于蛮夷，盛于华夏。
It is a custom of ethnic minorities to wear earrings. The purpose of wearing earrings is to remind women to check their lives. They act cautiously and later become the custom of Han Chinese, reminding women to obey women.
