I sometimes observe other people's writing methods. Seriously, the posture of holding the pen is largely related to the quality of writing, because some postures are difficult to draw a beautiful arc smoothly.
Words do not represent practice. You'd better study the habit of fingers carefully and correct the incorrect methods. I guess the way you hold chopsticks is also wrong, hehe.
Speaking of my handwriting practice, I remember it clearly. My handwriting was ugly in junior high school. Later, when I saw my classmate's beautiful handwriting and wanted to learn it, I went to the stationery store and bought a copybook (I remember that the copybook was recessed and my handwriting was copied along the concave line). I don't know why, but I wrote it less than two weeks ago. People say my handwriting is completely different. . )
After that, I like to use a ballpoint pen and a thicker pen, because it has more friction and is easy to write beautiful words.
I don't think it is necessary to write calligraphy upstairs. I have never practiced calligraphy. Besides, practicing calligraphy is very hard. Besides, I don't know how China's calligraphy will be after practicing calligraphy. I wish you success!
