What ancient poems are suitable for calligraphy? Thank you!

Your question is a little vague. Because there is no question of suitability. As long as it is a word, a brush and a pen can write, and the pen itself is used for writing. But I guess what you mean may be: suitable for writing with a pen. This is really a problem. Ancient poems with few words, such as quatrains, are difficult to write a poem into a work. Even if it can be written, it is a short sketch book. But we can write a few songs together. A work can write a long poem with more words, so design a composition. If it is regular script, first of all, we should design a few lines and columns, as well as the location of the inscription. It is necessary to give consideration to the upper level and the lower basic level of the running script (some people say that "there are ten years in the upper level and ten years in the lower level" means this) and the position of the last word, too high to be empty, too low to be blocked. Youku has an album of pen calligraphy and ancient poetry, and searches for the album of "Tang Poetry and Song Poetry"
