Correct format of vertical writing of ancient poems

The format is:

1, write the content, from right to left, from top to bottom, without punctuation, write directly down, and after writing, start another column and leave one blank.

2. After the content is written, write down the name, author and signature of the poem (in smaller words), leave a blank behind, and then stamp it. Be careful that the seal is not too big, and the size of the seal is similar to that of the signature.

The composition of vertical calligraphy is to fold the rice paper in half, leaving four margins at the top, bottom, left and right, and start writing from the top frame. When signing, write someone's poem (if it is a paragraph, write someone's poem excerpt), and then write down the time, who wrote it, etc.
