I want 10 children to learn calligraphy at home, but I don't know where to start. What copybook should I buy?

I am a calligraphy and painting major, and I am also teaching calligraphy. Give you some advice: At the age of ten, learn a book based on Tang Yan Zhenqing's Li Yanqin Monument. When you write it, it is powerful, small and powerful, easy to use, and you won't forget it once you get started. When writing, you can pursue some changes according to your own personality and hobbies, and you will be more interested and effective in learning. You can also brush with "books are geese" and "big white clouds"; Ink is "a virtue pavilion". Beginners use each other's paper for a few cents, and then use rice paper after the effect. Here, I wish the children early success.
