"The Book of Songs". The Book of Songs is catchy and easy to understand, while the classical prose is difficult to understand and difficult to popularize. Therefore, the Book of Songs is suitable for third-year primary school students. The Book of Songs is the beginning of ancient Chinese poetry and the earliest poetry collection. It collects 311 poems from the early Western Zhou Dynasty to the middle of the Spring and Autumn Period (11th century BC to 6th century BC).
