The Zhaba Earth Stockade of Mt. Immortal Blue is the longest-surviving matrilineal clan within the Beimang territory, where clan members have always been bonded by maternal blood relations. Marriages take the form of either group marriage or walking marriage.
Group marriage usually refers to the collective marital relationship wherein a group of men from one clan marry a group of women from another clan. After entering into group marriage, these individuals live together, and members of the marriage can freely cohabit without being restricted to any one male, and vice versa.
This marriage system is one of the most ancient among the Human Race, and in those obscure ages, it marked the Human Race's first attempt at imposing restrictions on the relations between sexes.
Perhaps it was from that time that humans began to distinguish themselves from common beasts, and then gradually proliferated and transformed, advancing step by step to become the dominators of the Xiehe continent.
