At present, there are only a few sand painting training institutions in China, and there are only a few well-known ones, such as Beijing Zanmin sand painting Dabao sand painting Sichuan arbitrary sand painting. Every family has a different style, so you have to find the right teacher to learn sand painting. If you really want to learn, please look for the sand paintings of the studio you want to attend the training. Choose your favorite style and teacher's training institution. At present, only face-to-face instruction is accepted. Because of the characteristics of sand painting, face-to-face lectures will be much faster than learning textbooks. In other words, you need to go to the training center to study in person. Another way is to buy textbooks at the place where sand paintings are drawn. You can study at home, but their textbooks are only partial. It's not all out yet. It seems that I am afraid of piracy or signing up for study. When enough local people sign up, I am not sure about other learning methods.
