How should calligraphy and painting be protected?

Because the materials used for writing and painting are paper, silk, twill and other fiber materials and silk woven materials, they are easily brittle and broken if they are old or poorly preserved. Generally speaking, calligraphy and painting are most afraid of moth-eaten, moldy, damp, water immersion and fire. Calligraphy and painting are easy to be damaged, so when hanging, rolling and storing calligraphy and painting, special attention should be paid to handling them with care. The ancients summed up some collection methods for us: for example, hanging paintings and calligraphy should be lightly swept with a ponytail broom or a silky broom every day, and must not be brushed hard to avoid stabbing the painting core. Don't open all the windows, lest the wind blow the picture directly. A small tablet must be placed in front of the hanging painting and calligraphy to protect it. Don't put anything that blocks the painting before the tablet. Only incense burners, pianos and inkstones should be placed. It is humid and sultry in the summer, so it is not suitable to hang paintings. In the cold, a heater should be built in the painting room to avoid freezing damage to paintings and calligraphy.

Be particularly careful when rolling the painting. Pay attention to the alignment of the mounting edges at both ends when curling. Don't use too much force to avoid paper and silk creases from breaking. You can look at the painting by holding up the back of the painting, otherwise the silk is easy to crack, and it is easy to drop the painting and calligraphy to the ground carelessly, causing damage. Calligraphy and painting should be placed on the top of a high cabinet at ordinary times, with good ventilation and away from the moisture on the ground. It is necessary to hang it in turn, which can not only be viewed, but also let the calligraphy and painting blow a little wind and see the sunshine, so as not to be moldy due to long-term winding. In rainy season, calligraphy and painting should be stored in a narrow wooden box and closed. The most difficult thing to do is to make the wooden box with fir boards. Don't paint and paste paper inside, so as not to be damp and moldy. The gaps around the affairs box are covered with paper, so as not to ventilate it and prevent white mold, or it can be stored in a vacuum bag. Should I put it in the cupboard where paintings and calligraphy are placed? Incense, papaya and the like, don't make raw moth. Generally, from the end of May to August, the quilt is covered with fine weather, ventilated in the shade, and then carefully stored, which can make the life of calligraphy and painting reach hundreds of years. ?
