1. stroke structure: a single stroke usually consists of one or more strokes. Pay attention to the structure and order of each stroke.
2. Stroke order: According to the basic norms of hard pen calligraphy, writing is generally from top to bottom and from left to right. Write the words next to singles in this order.
3. Pen skills: Hard pen calligraphy is written with a hard pen (such as a pen). Compared with soft pen calligraphy (such as brush), we should pay attention to controlling the pressure and angle of the pen tip to obtain clearer fonts.
Please note that these are just some basic precautions, and the actual writing needs to be adjusted according to the characteristics of specific glyphs. If you need to demonstrate the writing of single-sided glyphs, I suggest you refer to the related hard-pen calligraphy textbooks or video tutorials, so that you can better understand and learn.
