What background cloth is used for photography of Chinese opera?

There are many materials for making drama sets, including almost the most commonly used materials, including photoelectric technology. Because the scenes on the stage were really made of cloth at the earliest, the name "set" came into being, so that all the scenes on the stage, even those not made of cloth, were called sets.

The scenery made of cloth is made of ordinary white cloth, which can be unbleached white cloth or bleached cloth. After drawing various scenes on white cloth, there are two ways to make them. One is a relatively small scene, such as a screen, a wall or other flat scene. The painted scene is nailed to the wooden frame and tightened, and there are straps behind it to stand on the stage. The other is a larger scene, such as a hall and a big tree. The painted scene is first glued or sewn on the grid made of thread, and then hung on the hanger, which is higher than the stage when not in use and put down when necessary.
