公转 gōngzhuàn is achieved through the coordinated Rotation of different segments of the body. The revolution of the hand is performed in the Positive and Negative Circles. The analogy is to the Earth revolving around the Sun: It rotates once every day and revolves once every year.
The two directions of revolution of the hand are called 正旋 zhèng xuán and 反旋 fǎn xuàn.
