手再干净也含有油脂、汗渍、灰尘和霉菌等污染物，因此拿取书画要带手套，观赏时人与书画保持1.5米左右的距离，以免讲话时唾液飞溅到书画上。秋高气爽的季节，可以将收藏的书画取出掸尘、晾放，让吸收的水分挥发。

No matter how clean your hands are, they also contain grease, sweat, dust, mold and other pollutants. Therefore, when you take a painting or calligraphy, you should wear gloves. When you watch a painting or calligraphy, you should keep a distance of about 1.5 meters to avoid saliva splashing on the painting or calligraphy when you speak. In autumn, you can dust and air the collected paintings and calligraphy to make the absorbed water volatilize.

The protection of paper cultural relics is very difficult. Improper collection will damage the appearance of the collection. The ancients collected books with letter sets, calligraphy and painting with refined painting boxes. The materials for making the painting boxes should be carefully selected to prevent the oil in the wood from polluting the paper. In ancient times, the wood painting boxes were not only carefully selected (camphor wood is commonly used), but also made of multi-layer materials. The outer layer was camphor wood, the middle was nanmu, the inner layer was made of fine silk, and the paintings were wrapped with cloth.
