If the format of vertical writing is a metrical poem or a quatrain, which is two spaces lower than the text, there is no need to indicate the genre, because you can tell at a glance whether it is seven words or five words, a metrical poem or a quatrain. It is also possible to indicate the genre with a smaller font under the theme. (In some poetry collections, each topic is marked with genre and separated from the topic by a dot, which is determined by the style of the book. )
If it is a word, you can write the title with the word "low" in front, and mark the name of the epigraph with the word "send" in a smaller font below the title; Or add the word "send" after the name of the monument, and write it at the back of the word in a smaller font (another line), such as "send Qinyuanchun".
