If you really want to learn calligraphy, you'd better learn from your teachers, and they are teachers who have graduated from calligraphy major. They can teach you more systematically. You may hear others say that the handwriting of so-and-so elders or friends is good, but that's only what they think. The so-called experts look at the doorway, laymen watch the fun, and those who really write well are those who have profound skills or apprentices, who have received strict and systematic calligraphy education and worked hard. In addition, in fact, tools are also very important. First of all, if it is paper or paper, you can just use rough paper for beginners. I think the pen should be the most important. If you want to buy a brush, I suggest you find this article and read "Top Ten Brush Brands in China (with Selection and Maintenance Methods of Brush)". The article details the selection and maintenance methods of brush. I hope it helps you.
