Ci is an art form of poetry and a style of China's ancient poetry, also known as Song Ci, Quzi Ci, poetic style and long and short sentences. Nanliang, which began in the Southern and Northern Dynasties in China, was formed in the Tang Dynasty and reached its peak in the Song Dynasty. At first, it was sung with music, so writing lyrics is also called lyrics, relying on sound. Later, it gradually became independent and became a special art of poetry.
After the Song Dynasty, it can be said that long and short sentences are aliases of words, but in the Northern Song Dynasty, long and short sentences are the real names of words. In the Tang Dynasty, long and short sentences were still a poetic noun.
Some dictionaries say that "long and short sentences" are "aliases of words". Or note "long and short sentences" as "irregular sentence poems". Not both of these notes are correct. After the Song Dynasty, it can be said that long and short sentences are aliases of words, but in the Northern Song Dynasty, long and short sentences are the real names of words.
In the Tang Dynasty, long and short sentences were still a poetic noun. The so-called "long and short sentences" and "long and short" have their specific meanings and cannot be vaguely interpreted as "uneven length".
