What is the format of brush calligraphy?

The last paragraph is in the upper right corner. You can write such things as Yazheng and Bojian, and then you can write your own creation time, your own name and so on in the lower left corner. For example, Xin Mao nian chun so-and-so book. Add your own seal. The key is that the previous paragraph cannot be higher than the top of the text of the work, and the next paragraph cannot be lower than the bottom of the text. The size of the seal should be similar to the font of the signature. Not too big or too small. In addition, the general principle of signature font is that the text is regular script, and the signature behavior is regular script or regular script. If the text is cursive or running script, sign in block letters!
