• Summary: This article introduces basic tenents of Confucianism and its evolution, and explores its unique contribution to socio-cultural practices on gender-based oppression in social work practice.

• Findings: The yin-yang (陰-陽) relation is originally a cosmic idea that is cyclical and harmonizing, but not oppositional and contradictory. The yin-yang binary is not intended to indicate any human relations (gender) or political ethics but the harmony of human nature. Despite the complementary nature of the yin-yang union, a confucianized Chinese society consigned yang to male and yin to female, signifying hierarchal gender relations. Women were considered inferior to men in the patriarchal family system. Misinterpretation of Confucianism promoted hierarchal relationships between men and women and, as a result, dramatically affected the gender-based attitudes and behavior.

• Applications: Confucianism, one of the most crucial philosophies of Asian cultural norms, has long been studied from the perspectives of intellectual history and philosophical truth seeking; however, only a few scholarly texts are available in the area of Confucianism and its influence on gender inequality. In particular, this article attempts to help scholars and helping-professionals understand how the harmonious yin-yang concept evolved into the contradictory binary, which further perpetrated gender hierarchy and oppression toward women. Limitations of current Confucianism research and implications for social work practice are presented.
