Take my father's experience of practicing calligraphy as an example. My father's handwriting used to be very thin, without any strength, and it looked illusory and without any masculinity. He also had nothing to do, so he bought two copybooks to practice, just to cultivate self-cultivation.
I didn't expect him to be addicted to practice. Every day, he will write for more than an hour, writing one article after another for copybooks, and sometimes recording news on TV and constantly practicing the words on copybooks. He persisted for four or five years, and now the font is completely different. If you look through his previous words and compare his current words, you will find that it is completely different from a person's words.
After seeing that my father's calligraphy practice was so effective, I also started to buy some copybooks, first tracing a few pages, and then copying these words in other books. Some words are well practiced and can be used when writing, but some words can't be changed. Copying copybooks may take time, so don't be impatient. Write and practice when you are free every day.
