What are the four books of Biyong in the Western Zhou Dynasty?

Biyong's "four learning" are: learning music, learning books, learning oriental martial arts, badminton and etiquette. The four-learning system also has the significance of setting up teaching in different subjects. However, the teachers in the four schools are still government officials, and they are teachers' responsibilities, not teachers' responsibilities in a special sense.

The vassal Pan Palace is a semi-system, with water in the east, west, north and south, like a half wall. The nature and function of Pangong are the same as Biyong Palace, and it is the center of political and religious activities in vassal states. The poem "Truffle Dishui" records Lu Xigong's "Pangong", where he watches drinks, preaches the good prescription of governing the country, gives prisoners, preaches and teaches, and handles government affairs. This is the most detailed record about Pan Palace in Zhou Dynasty.
