Can first-grade children learn calligraphy with pens?

Children in grade one had better learn hard pen calligraphy with pencils. First of all, they are easy to make mistakes and can be deleted. Second, it is not as fast as a pen, and it is easy to get dirty; Third, the pencil can be thick or thin, sharp or blunt, making it easier to write. My own opinion is also based on experience.

The above is the comparison between pens and pencils: the pen above is written by a junior, the pencil in the middle is written by a sophomore, and the pen below is written by a sophomore. It can be seen that although the first-year students write well, they still make mistakes and can only cross; The bottom one also travels frequently, and he uses correction fluid; In the middle is a small classmate on a business trip, but it can be wiped.
