Confucianism (儒家思想) has been followed by Chinese people for more than two thousand years.
To help people understand how to behave towards others, Confucianism teaches the Five Constants (五常). These are ren, yi, li, zhi and xin. They are general virtues (美德) around the world. The most important two are ren and li.
Ren is the feeling of care and love we should have for others. Confucius explained ren could best be understood as loving others. He is famous for teaching people "What you do not want done to yourself, do not do to others". It is quite similar to what is known in the West as the Golden Rule (treat others as you wish to be treated).
While the meaning of ren is easy to understand, li is a little harder to express. It can be thought of as duty or even respect. Generally, li is the way we should connect with people in our everyday life. In Confucian writings, discussions about li include the proper way to drink tea and how to remember ancestors (祖先). While ren is mostly about our opinions and feelings, li is about how we express our opinions and feelings towards others and towards the world around us.
Perhaps the most well-known Confucian virtue is xiao. This is the duty children have to their parents. Xiao means loving, respecting, obeying and taking care of one's parents in their old age. In Confucianism, xiao is important for a harmonious (和谐的) society: Without it, the whole world would fall into a mess.
