Tai chi is a centuries-old Chinese martial art and an internationally popular form of exercise. It is a series of postures (姿势) and motions that develops one's (strong)and flexibility through careful, flowing movements and focused breathing. Each posture (slow) transforms into another, and we gradually need to shift our weight (maintain) balance. At the end, we return to the starting position: in other words, all of the movements (connect) in an endless, continuous flow.
The practice of tai chi is rooted in (tradition) Chinese philosophy, particularly the ancient concept of yin-yang. The tai chi symbol, or taijitu, (show) yin and yang together: yin symbolizes the dark, female force in nature, yang represents the bright, male force. Yin cannot exist without yang, and yang cannot exist without yin. Tai chi aims to achieve balance opposites in life: yin and yang; soft and hard; mind and body, and so on. At the heart of tai chi is the concept of qi, generally translates as "vital energy". The different exercises help move the qi through your body, (produce) positive effects on one's mental and spiritual health.
