This war is not right. Everyone should be peaceful with one another! I will set off on a journey to spread this belief.
And so Confucius set off to teach people about his principles including the Five Relationships.
We should all respect one another and establish peace and harmony. We should follow the five relationships in which harmony would be established if everyone follows their roles. No relationship is equal besides friendship.
With the five relationships, there would be political as well as social order and harmony. But not only that he believed that parents should be respected and that a ruler must set a good example for his people.
And so him and the people his words impacted and who decided to follow Confucius in Confucianism traveled to neighboring nations to spread his word.
