If you are a student now and your studies are not very tight, you'd better stick to 100 words every day. If your studies are tight, that's fine. It's summer vacation, so we should practice every day, and we should practice every day in the future (it's more convenient to go to work, not afraid of fatigue and trouble, and the effect is the same every night). At the beginning, the most important thing is to post first. Although it doesn't seem to have much effect, it is actually practicing your basic skills and your "hardware" (to put it bluntly, you practice different strokes of different words, but you don't specialize in strokes, so you can't practice anything, because even the same stroke is different in different words or even in the same word, depending on the situation, so you have to practice the whole word), thus laying the foundation for the later work. If you are still studying after practicing for several holidays, you'd better find a class teacher and choose a classmate who writes beautifully to sit at your desk (work doesn't matter, and so does a handsome colleague), and he should like to write what he writes every day, read her handwriting more, copy more, ponder more, consult more when necessary, and try to find opportunities to practice more, because although you were in the copybook before, it was difficult for ordinary people to learn calligraphy. Therefore, the handwriting of peers is the best to learn. Generally speaking, if you study hard when posting in front, lay a good foundation and be moved by your deskmate later, I can guarantee that your calligraphy will make a qualitative leap in two months and form your own font, not just a beautiful problem.
As for the pen that should be used, of course, it is a pen (not too good, just starting to practice, you need to find your most comfortable posture to hold the pen, and it is not cost-effective, saying that a too good pen can't be broken in a day, not enough to open a shop! The words are all practiced, and the good ones will be used for a long time, because the hard pen is the foundation of the soft pen.
This is my experience.
