The yunshou (cloud hands) is the very first skillin the training of a xiqu (Chinese opera) actor/actress. It requires coordination between the hands and the arms, and extends to involve a set of conventions, including a specific gesture, glance, posture, and step. In fact, the yunshou is a fundamental posture that all movements of the upper limbs are based on. In this paper, I suggest that yunshou deeply embodies the aesthetics of "roundedness" in traditional Chinese theater. The basic set of yunshou can be divided into six to ten steps. For a beginner, learning the basic version enables one to move on to learn the different versions of yunshou. There are currently more than ten sets of yunshou that are extended from the basic set, and if stage props are used, the number of yunshou-derived movements further increases. This study explores how yunshou embodies the Chinese aesthetics of "roundedness" both internally and externally. As a beginner's item, it transforms the actor's body from an ordinary one to a body of the theater stage. Most importantly, since the shape and the mood of yunshou differ from one role type to another, learning the yunshou in details helps instill the physical behaviors of a designated role type in the beginner, thereby preparing him/her for advanced training.
