You can go to the bookstore to buy a small Copybook for calligraphy, such as The Classic of Ling Fei or Wang Xizhi's Ode to Le Yi. Get up early for half an hour every day, write carefully, persist for one year, and achieve fruitful results.
However, you should also pay attention when writing at ordinary times. If you want to record quickly, you can find some running script copybooks, or cut grass songs, recite standard Chinese abbreviations and write quickly. Don't recite the abbreviation of a word at will, which is unprofessional. You can master all the common words in one year.
Again, persistence is the key, and it is ineffective in a short time.
Pencil friction is large, but the pen is slippery, so you can't master the pen well.
Writing askew is the problem of composition, because you pay too much attention to strokes and are not sure about the starting position of a word, and it is also a kung fu, which requires long practice.
