Second, if it's an official book (Kai, Li, Chuan), take the method of mending. Specific operation method:
Dig it out and make up the same rice paper.
Mining method:
1. Wet the part to be cut with an unused brush ring, and then lift it by hand and gently tear it off; In order to make it thinner from the inside out, if it is not ideal, you can scrape it gently at the edge with a knife;
2. Prepare a piece of rice paper with the same texture and larger size as the patch, and lift it with a brush ring dipped in water and tear it off. The edge of the patch is larger than the cut part, and basically the edge of the patch is similar to the scraping edge of the original tear part; It should be noted that no matter whether your patch is square or round, it should be consistent with the grain of the painted rice paper;
3. Apply a circle of thin paste to the thinned part of the edge;
4. Turn the painting center upside down and put the patch flat behind the painting center to ensure that it is firm and bubble-free;
5. Cool to a flat place and let it dry naturally. After drying, first check whether the paste is reliable and smooth. If it is uneven, you can iron it with an iron. If you don't have an iron, you can use a tin or stainless steel teapot with boiling water as an iron, and the bottom of the pot must be wiped clean!
6. You can also use an iron to dry and iron.
In this way, there is almost no trace of repair, which is invisible to most people. The master made it, even if it is photographed in the sun, there is no trace of digging.
