As far as I know, hand painting is a technical job. Learning well requires patience. My friend now runs a calligraphy and painting mounting shop, and the business is very hot. You Baidu search Beijing Juxiange Painting and Calligraphy Institute. I learned it in their painting and calligraphy institute. You have to ask for details. I hope it helps you!
A complete Chinese painting needs to be more beautiful and convenient for preservation, circulation and collection, which is inseparable from mounting.
