Why did Yan Zhenqing become a calligrapher?

When Yan Zhenqing was a child, his family was poor and didn't have much money, but he liked calligraphy very much. Every time he writes a letter, he writes it carefully. Seeing that he is so eager to learn, his father often teaches him to write. It's a pity that Yan Zhenqing's family is too poor to afford pens and paper. His mother was so anxious that her hair turned white. She knows that the child will succeed in the future, but she has no money for him to read and write. Yan Zhenqing is very sensible. He dug some yellow mud and put it in a porcelain bowl. The mother looked at the sensible child with great pride and pride. Liu writes every day, and he washes the white wall again and again. Sometimes he writes and draws on clothes and even washes them out. It is precisely because of Yan Zhenqing's earnest study and assiduous study of the writing spirit when he was a child that he finally became a great calligrapher.
