You can work hard on the recruitment of painting and calligraphy training classes and find a job as a painting and calligraphy teacher. Or have the ability to start their own businesses and run training courses. This job is easy. If you like painting, it will be a pleasure. Nowadays, parents of children are very willing to spend money in this area. I suggest that you can develop in that area. . .
