On the basis of practicing boldface characters, mastering the structure of characters, and practicing basic skills, you can choose your favorite font for practice. The process of selecting fonts is called calligraphy selection. On the basis of calligraphy selection, there are five steps of reading, tracing, copying, memorizing and creating.
We all know the pronunciation of the Chinese characters on the post, so there is no need to read them again. What I read is the shape, structure, and strokes of the characters, and analyze and figure out the characteristics of the strokes of the characters and the relationship between the strokes. For example: when we read "中" in boldface, we need to read that the vertical line of "中" passes through the middle of "口".
The character "口" is slightly flat, and the horizontal length is twice the vertical length. The long vertical part in the middle is divided into two equal length segments by the lower horizontal of the character "口", and the upper segment is divided by the "口" character. "The upper horizontal line of the character is divided into two sections of equal length. This is reading glyphs and structures. Different fonts and strokes have different characteristics. The changes in hard-pen calligraphy strokes are not obvious and are not easy for middle school students to master, so I won’t go into details here.
"Tracing" refers to tracing red, that is, beginners use a blue pen to trace along the handwriting on the printed red copybook. "Copy" refers to copying, that is, covering the model characters with transparent paper, and writing stroke by stroke along the shadow of the characters on the paper, which is also called copying.
