The only secret of practicing calligraphy is: persistence!
The fonts of hard pen calligraphy are regular script, running script, cursive script, official script and seal script. Running script and regular script are more practical. Cursive writing is a little bit difficult, and it needs someone with a little foundation to write. Official script and seal script are even more difficult to write, which is not very practical in life. So choose your favorite font, plus serious practice and long-term persistence, there will be no bad words.
Adults have actually formed their own writing patterns, and it is not easy to change them. Regular script is characterized by square and straight strokes, which can be used as a model.
Regular script is suitable for people with poor foundation, just like Shujun's son, who is in the third grade of primary school. It's like a toddler. If he can't even walk steadily, it is impossible to run.
Therefore, people who are basically poor should practice regular script, buy regular script stickers in scarlet letters, and practice only one hour less every day.
