"Huan" means washing, and "yarn" can refer to both a kind of cloth and clothes.

This sentence originated from an ancient historical allusion in China, which described the scene of beautiful Yue Shi washing clothes by the river during the Spring and Autumn Period and the Warring States Period. The clear river reflects a beautiful figure, which makes her look more beautiful. Even the fish forgot to swim when they saw her reflection and finally sank to the bottom of the river.
