History: Chinese iron balls have long been famed as one of the “three treasures” of Baoding, China . First produced during the Ming Dynasty (1368-1644), iron balls have often been improved through the ages by skilled Chinese handicraftsmen. Originally, these balls were simple, ringing cylindrical objects. Later, handicraftsmen began designing hollow balls and inserting sounding plates that produce high and low tones when used. These lighter balls are easier to handle and the musical tones contribute to the relaxation process that results from exercising with them.  
Directions: The balls are placed in one’s hand and rotated in either a clockwise or counterclockwise direction. This exercise will keep all of the points in one’s hands in constant motion. With the muscles in one’s fingers and forearms contracting and relaxing harmoniously. Beginners should select balls of a smaller size and then, over time, increase ball size as one’s proficiency improves. Ultimately, one can exercise both hands alternately or simultaneously and may even choose to use three or four balls in one hand.  
Maintenance: The balls are made of metal and, hence, should be kept dry and clean. Although the balls are strong and durable, owners should avoid violently knocking them against each other and against other solid objects and surfaces. If one plans not to use them for a long period of time, it is advisable to coat the balls with wax or grease for maintenance and preservation.
