Silk-Reeling exercises (chan si gong) found in Chen style Taijiquan (Tai Chi Chuan) consist of spiral movements combined with the internal flow of qi and the external motion of rotation.  These exercises help to open the eight channels, improve the yin and yang balance of the body, and smooth the blood flow.  These exercises internally help the mind to lead the qi and externally help strengthen the body and develop core Taijiquan posture and skills.
