Black cloth absorbs all light, so it doesn't develop color. Bask in the quilt covers it to absorb heat, which makes it easier to dry. Covering the furniture with black cloth is to cover the dust and prevent the furniture from being deformed by moisture.

Sometimes, due to weather conditions, floors and walls will regain moisture, and moisture will re-test floors and furniture, causing physical discomfort and even affecting the quality of life, so it can be covered with cloth.
