太极 (tài jí): the Absolute or Supreme Ultimate, the source of all things according to some interpretations of Chinese mythology

Grandpa practices tai chi in the park every morning; his movements are slow and fluid, and many neighbors join him.

In Chinese philosophy, the Supreme Ultimate is regarded as the origin of all things in the universe, representing the unity and balance of yin and yang.

In the center of this ancient painting is a taiji diagram, with black and white colors encircling each other, symbolizing the harmony of opposing forces.

He has practiced tai chi for ten years; his body has become more flexible, and his mind has become calmer.

Tai chi is not only a martial art but also a way to cultivate the mind and character, emphasizing overcoming hardness with softness and combining movement and stillness.
