Vertical arrangement is a special typesetting method, which arranges characters vertically from top to bottom, and each word or word occupies one line. In the vertical format, each line of text is generally written from right to left, with the last word or word written first and gradually written upward until the whole poem is written. This format is common in China's ancient calligraphy, painting and printed works, giving people a unique artistic aesthetic feeling. Vertical ancient poetry can also be used in modern literary creation, showing a simple and classical style.
