If it is cross-stitch framing, it can be done in three days. Generally, two weeks is enough for mounting basic Chinese paintings. You can get familiar with it as long as you work hard for a month, but you must work hard. If you study art, you can go to a bigger mounting shop or gallery. Tuition is generally two or three thousand yuan, and the semester is almost one month. You can also be an apprentice. It's best to have an acquaintance introduce you. Those who are expected to sign a contract with the gallery must work in the store for at least a period of time. That's understandable. The boss can't teach you for nothing and teach your apprentice to starve to death. There are many styles of Chinese painting mounting, including Tang mounting, Song mounting, and uncovering and mending. After learning the basic skills, you have to learn by yourself. If you want to do a good job, you must work hard.
