In Confucianism, the Sangang Wuchang (Chinese: 三綱五常; pinyin: Sāngāng Wǔcháng), sometimes translated as the Three Fundamental Bonds and Five Constant Virtues or the Three Guiding Principles and Five Constant Regulations, or more simply "bonds and virtues" (gāngcháng 綱常), are the three most important human relationships and the five most important virtues. They are considered the moral and political requirements of Confucianism as well as the eternal unchanging "essence of life and bonds of society." Source: Wikipedia (en)
