Cultural Insight:
You might have seen many Chinese people in parks practicing Tai Chi slowly and softly. Tai Chi is not just a form of exercise; it is a philosophy. Its movements are slow, but they contain the inner principle of "using softness to overcome hardness" – the soft can overcome the hard. The Tai Chi symbol is the yin-yang fish, representing the balance and cycle of all things. Practicing Tai Chi can strengthen the body and also calm one's mood.
