Wang Qingren is famous in two areas of medicine. First, he promoted the importance of accurately understanding anatomy in order to diagnose and treat disease. Disection and surgery had been all but ignored since the time of Hua Tuo and traditional Chinese doctors had relied on a projected idea of the internal organs. Wang said that 'attempting healing without knowing the internal organs is is like a blind man walking in the dark.' He also strongly promoted the idea that many diseases were due to blood stasis and by activating blood circulation and clearing away the static blood, one could resolve even the very serious diseases. His blood vitalizing formulas are still used extensively.
