This is a Chinese book, but I think it's a good book that allows you to systematically learn the classics, as it is written with illustrations and divided by features. Each character is displayed large in a square, and there are ruled lines, making it easy to learn. This is a rare book that is not widely available in Japan. It is 88 pages long. Discounts are available for multiple purchases with other books. I am also selling calligraphy supplies. I would appreciate it if you would follow me and take a look.
