What classic Chinese studies are suitable for middle school students to study?

The Analects of Confucius, "The Great Learning" and "The Doctrine of the Mean" are recommended first, followed by "Guanwen Guanzhi", "Tang Poetry and Song Ci". Among them, "The Analects" and "The Doctrine of the Mean" actually require some life experience to gain a deeper understanding of its connotations.

However, I think "300 Tang Poems" is a must-read for middle school students.
