How to write a good hand with a brush?

Sharp tools make good work. Parents are willing to invest, and I have higher requirements for tools. The pen is a custom-made wolf-hair inkstone made from an old inkstone in the 1980s, and the ink block is the old Mo Gong smoke oil fume 10 1 from Shanghai Ink Factory. The paper is mostly made of manual raw edges, and the rice paper is Red Star old rice paper. You can see that I am very inclined to old things. Because there are a lot of lost technologies in both tools and calligraphy and painting, few people will pay attention to these in modern times, so the paper making and ink making processes are not as good as before. I have heard a saying to the effect that if you write well, don't pick a pen and paper. In a sense, I am in favor, but I am not absolutely in favor. I have met people who are used to using inferior paper and pen, but can't write with good paper and pen.
