Where did the painting and calligraphy restorer learn?

The first thing depends on where you are. The best in China are Rong Baozhai, the Forbidden City and Liulichang. Mounting repair technology is also called uncovering, which requires very thick mounting technology and artistic calligraphy skills. It usually takes years of experience. I suggest starting with calligraphy and painting mounting instead of learning machine mounting. Handwork is the best choice. I have been engaged in painting and calligraphy mounting for more than ten years, and I will exchange qq4 19680978 when I have time.
