There are two kinds of leggings: one is the' leg strap' that the old people tied at the trouser leg in the early years, the main purpose of which is to tighten the trouser leg and keep out the wind, so that the fat trousers are tied at the trouser leg and the whole body is much warmer; The other is the "leggings" continued by the army before liberation. Roll up the trousers from the ankles in turn until they are close to the knees. This is called leggings. This kind of' leggings' is directly wrapped layer by layer, which is called' bowstring'; The other is to twist the bag every time, just like paper, and fold a mark every time. Finally, a row of diamond-shaped patterns will be left. This winding method is called "pattern weaving".

The' circular' winding method is easy to loosen when moving, so it has to be stopped and rewound.

Although the' pattern' is slower, it will be stronger and should not be loose.

This practice of leggings had been going on for many years before liberation. Later, it was slowly cancelled.
