阳 (Yang) is a fundamental concept in Chinese philosophy, particularly in Taoism and Confucianism. It represents the active, bright, and masculine principle in the duality of Yin and Yang. Yang is associated with qualities such as heat, light, and movement, symbolizing energy and growth. In the context of Chinese medicine and martial arts, Yang is often linked to health and vitality. A balance between Yin and Yang is essential for well-being, as an excess or deficiency of either can lead to physical or emotional issues. Understanding Yang helps in achieving harmony in various aspects of life.
