Pastoral Song Introduction: In a matrilineal clan society, people "only know their mother but not their father", forming a blood relationship around women. In Banpo, people's daily life also revolves around women. In this primitive public ownership society where class divisions and hierarchical distinctions have not yet been formed, people "farm and eat, weave and clothe, and have no intention of harming each other." Despite the relative scarcity of materials, it presents a picture of equality, stability and harmony in the early days of agricultural society.
