What about the sleeves?

The pinyin for smooth sleeves is: Luxiùzi.

Roll up your sleeves, pronounced Lu instead of Lu, which means to roll up your sleeves in Chinese. The word "Liu Yeer" in the second volume of Chinese for Grade Seven has the same meaning as a rolling pin.

Sleeve smoothing is an act, which means to put all the sleeves at the arm position. Such long-term behavior will affect blood circulation, leading to blocked blood circulation in the arm. Poor blood circulation will cause difficulty in blood circulation, and symptoms such as numbness of hands and arms will appear.

When I say you can't open your sleeves and legs, I mean in public or formal occasions. Usually you are at home, there is no reason to care what you want.

People often wear clothes and seldom stroke their sleeves. There are probably several reasons for smoothing sleeves: First, because of the hot weather, I broke out in a sweat and smoothed my sleeves to cool down. The second is to wash your hands and face, afraid of getting your sleeves wet and smoothing them out.

Third, sometimes when moving things, doing heavy work, or wrestling hard, it is inevitable to roll up your sleeves and have a good look. The fourth is heartless. In order to fight fiercely, the sleeves were pulled up to show their brute force.

This habit is not suitable for winter. When touching, the arm is cold, and the touching time is very long. The sweater is not broken, but the sleeves are loose and deformed first, which is not nice.
