The period of the Spring and Autumn and the Warring states is a time of profound changes of ancient social structure and
ideology.As an important component of social structure,family systems also develop accordingly.From Shang Dynasty to the early period of the Spring and Autumn period,any individual is drowned in families and there is not
individual consciousness at all.In the middle and late period of the Spring and Autumn period,a crack began to appear in the integrity of the consanguinity family and at the same time the
Consciousness of a family became dim gradually.In Warring States period,the family further crumbled.The patriarchal clan system and clans were treated with indifference.The relationship between home officials and masters evolved from loyalty to contract.The personal signet and graveyard emerged.Persons shook off the yoke of families and go from place to place to look for free development.The indifference of the family consciousness and the awareness of individual consciousness fleck the profound social changes of that time,which settles the foundation of the development of ancient ideology and then influence the history of China.
