I have already worked, and I want to learn Chinese calligraphy as an amateur.

Buy a similar pen, ordinary paper and ink. Although I don't like strokes, I'd better practice regular script for a while. If you don't know all kinds of fonts, just pick one and practice it first.

Of course, the basic skills of pen writing are helpful to the font structure, but only by mastering the basic skills of brush writing can it be effective.
