Answer: Confucius believed that if people acted according to the five relationships, social order and harmony would be restored in China.
Explanation: Confucius was born in 551 B.C. He lived in a time in China when there was violence and the older values from the Zhou Dynasty were no longer being respected. Confucius was a teacher and wanted to restore harmony and thought it would be achieved by respecting the five relationships that would organize society, these were the relations between:
1) ruler and subject, 2) father and son, 3) husband and wife, 4) older brother and younger brother, and 5) friend and friend.
He created a code of proper conduct for each of these relationships.
The ethical system created by Confucius became the base for chinese government and social order.
