The education of the children of emperors or princes in the Western Zhou Dynasty can be roughly divided into three stages: in the first stage, children aged 6 to 9 study at home, learning simple numbers, middle names in the southeast and northwest, heavenly stems and earthly branches and so on. The second stage, 65,438+00 years old, entered the primary school, mainly studying writing, counting, music and dancing. This is the custom of following the clan commune to train children to stay outside. In the third stage, 13 years old is an adult child, and it is time to enter the university.
