The old tree is still there, and old boys is gone, which shows that the years have passed quickly.
Poetry is a genre of ancient Chinese poetry, also known as ancient poetry or ancient style, which refers to a genre of poetry that originated before the Tang Dynasty and is opposite to the modern poetry that appeared in the Tang Dynasty. Its characteristic is that the metrical restrictions are not too strict. There are many styles of ancient poetry in China, and there are different opinions on the classification and appellation of ancient poetry. Especially for Yuefu, ancient style and ballad poetry, it is even more confusing. Because, from the formal point of view, Yuefu style and ancient style are both five-character styles, and seven-character ancient poems and ancient songs are all seven-character styles, so it is difficult to distinguish them. But since ancient times, people have unanimously recognized their differences in content, technique and style, and established their names.
