What is the word of Tik Tok's shallow turtle calligraphy and painting?

Calligraphy and painting belong to a particularly delicate category of antiques. It is expensive because it is a pure work of art, and some celebrity calligraphy and painting are rare treasures. Because the materials of calligraphy and painting works are all fibrous paper and silk, acidic substances such as animal glue, starch and paste are added when making paper or mounting calligraphy and painting, calligraphy and painting works will become moldy, moth-eaten, faded, yellow, aged and brittle after being exposed to moisture, light and heat. It can be seen that mastering the maintenance of calligraphy and painting is very helpful for collecting calligraphy and painting.

When collecting calligraphy and painting, don't touch the works directly with your hands. Wear gloves to prevent the calligraphy and painting from being polluted by sweat and scratched by your nails. Avoid direct sunlight when appreciating calligraphy and painting. Calligraphy and painting should not be opened and closed too hard. If there are creases, you can spray some water on the back of the calligraphy and painting to make it wet, then stick it on the glass to dry or iron it with a low-temperature iron to eliminate the creases. Pay attention to moisture-proof, light-proof and dust-proof when storing calligraphy and painting. The storage room should be kept at an appropriate temperature and humidity. The intensity of lighting should also be controlled. Calligraphy and painting treasures are best kept in boxes and in the shade. Don't see the light easily.
