What format is used to write five-character poetry calligraphy?

Calligraphy works generally write banners. The main body of the five-character rhyme is 40 words, and there are many words, so it should be calculated before writing. It is customary to write vertically, arranged from right to left. Leave a ceiling at the top and a foot at the bottom. The ceiling should be wider than the feet. Every line should be written from the zenith to the soles of the feet, and it should not be uneven. The last line can't be full, and you can't write one or two words, but more than two words. There are the same words in metrical poems, which should be written in different languages, with the same radicals and different writing forms. In a work, write no more than three words with long vertical lines, and avoid aligning lines with long vertical lines. Inscriptions should be in running script font, smaller than the text font. You can write the first and second paragraphs, or you can just write the next paragraph without writing. The previous paragraph can be written on the right side of the text, the next paragraph can be written on the left side of the text, or both the previous paragraph and the next paragraph can be written on the left side of the text. The beginning of the signature should be one or two words lower than the text. The position of the author's seal should be between the author's seal and his name, and the seal should not be lower than the text. So there must be a plan for signing.
