Health - promoting balls are generally two small metal balls, with different sizes, models and weights. They originated in the north during the Jiajing period of the Ming Dynasty, about 500 years ago. At that time, there were already red - furnace workshops making fitness balls in Baoding Prefecture, Hebei Province. Therefore, health - promoting balls are also known as Baoding iron balls. There is a legend about the invention of health - promoting balls. The blacksmith Wang in Baoding Prefecture, in order to repay an imperial censor who had rescued his daughter, forged a pair of iron balls after dreaming of being guided by Sun Simiao, the King of Medicine, and gave them to the imperial censor who had suffered hemiplegia after a stroke. By constantly rubbing the iron balls every day, the imperial censor gradually recovered, and health - promoting balls became popular from then on. Although this legend is somewhat exaggerated, it shows that the birth of health - promoting balls was not accidental, but was based on people's accumulation of some similar experiences before.
