Are good paper, pen and ink important for good calligraphy?

Only with good paper can we have better layer penetration effect;

Only with good pen can we turn freely and do whatever we want;

Only with good ink can we achieve black and white And like new, rich in layers.

Therefore, the quality of paper, pen, and ink is very important for calligraphy practice and creation. For example, a poor-quality writing brush, no matter how tall your handle is or how thick your brush is, will never produce the effect you want.
