Introduction to the Tai Chi Altar: The Tai Chi Altar is a landmark building of Taoism. The large Bagua diagram on the altar interprets the hardness and softness of social life, movement and stillness, life and death, comings and goings, rise and fall, etc. based on the basic teachings of Taoism and the theory of yin and yang and the five elements. When two people stand on the "fish eyes" with black and white Bagua patterns and talk, they will receive a magical sound transmission effect.
