[Wu Zhong-guang and studies on his works on pulsology]

The Mai fu jie yi (Decipherment of Pulse-taking in Verse) which was long lost, has been found existed in Zhen mai xu zhi (Introduction to Pulse-taking) This 5-volume extant citation has been allegedly claimed to be compiled by book merchants and contains several pulse works written by Wu Zhongguang, because Wu's book is included as the 1st volume of the whole book and Wu is also recognized as living in the Ming dynasty. Included together with Zhu mai xu zhi (Essentials of Pulse-taking), it has been investigated that the latter is actually a book with its title changed from Cha bing zhi nan (Directory for Diagnosing Diseases). There were 3 physicians bearing the name of Wu Zhongguang, but the other 2 has different native town and didn't write any book on pulse-taking.
