The Five Bonds
0. Ruler to Subject
0. Father to Son
0. Husband to Wife
0. Elder Brother to Younger Brother
0. Friend to Friend

Specific duties were prescribed to each of the participants in these sets of relationships. Such duties were also extended to the dead, where the living stood as sons to their deceased family. This led to the veneration of ancestors. The only relationship where respect for elders wasn't stressed was the Friend to Friend relationship. In all other relationships, high reverence was held for elders.
In time filial piety was also built into the Chinese legal system: a criminal would be punished more harshly if the culprit had committed the crime against a parent, while fathers often exercised enormous power over their children. Much the same was true of other unequal relationships.
The main source of our knowledge of the importance of filial piety is The Book of Filial Piety, a work attributed to Confucius and his son but almost certainly written in the 3rd century BCE. Filial piety has continued to play a central role in Confucian thinking to the present day.

The term jūnzǐ (Chinese: 君子; literally "nobleman") is crucial to classical Confucianism. Confucianism exhorts all people to strive for the ideal of a "gentleman" or "perfect man". A succinct description of the "perfect man" is one who "combines the qualities of saint, scholar, and gentleman." In modern times the masculine translation in English is also traditional and is still frequently used. Elitism was bound up with the concept, and gentlemen were expected to act as moral guides to the rest of society.
They were to:
0. cultivate themselves morally;
0. show filial piety and loyalty where these are due;
0. cultivate humanity, or benevolence.
The great exemplar of the perfect gentleman is Confucius himself. Perhaps the tragedy of his life was that he was never awarded the high official position which he desired, from which he wished to demonstrate the general well-being that would ensue if humane persons ruled and administered the state.
The opposite of the Jūnzǐ was the Xiǎorén (Chinese: 小人; pinyin: xiǎorén; literally "small person"). The character 小 in this context means petty in mind and heart, narrowly self-interested, greedy, superficial, or materialistic.
