1. Wang Xizhi: The shape of the characters should not be wide at the top and narrow at the bottom. If so, the emphasis will be disproportionate. The partitions are white, and the distance should be balanced, so that the top and bottom can be accommodated, and it will be naturally stable.

2. Yan Zhenqing: When you want to calligraphy, you should anticipate the shape of the characters and arrange them to make them stable, or unexpectedly create them and make them have different trends. This is called cleverness.

3. Chen Yi: If the sparse place is full, the dense place will be lifted; if the flat place is full, the dangerous place will be lifted; if the pressure is full, it will be fat, and if it is lifted, it will be thin.

4. Zhang Huaijin: Yan Yang and his back; that is, the two characters are combined into one character, and it is necessary to draw the upward and downward Yan Yang with the force of clutching and joining.

5. Wang Xizhi: When the two characters are combined into one, the weight should not be long, the single should not be small, and the complex should not be large. Dense is better than sparse, and short is better than long.
