I highly recommend Igor Simonov's Skype class for understanding the PRACTICAL use of Ying (Rong) and Wei circulation, based on Nan Jing. You can learn to feel whether either of these 2 Qi is active at any time in each meridian, and on which side of the body. The signal is present in the pulse. How to apply this knowledge depends on first making a diagnosis, and there are many schools of thought about that.I have been using Igor's teachings with notable benefit to my patients.

The seminar was extremely useful. A lot of interesting and new information for me. I have previously taken several pulse diagnosis seminars without any satisfaction (including Jimmy Cheng's pulse diagnosis seminars). I felt lost and confused. Your seminar offered a practical, relatively simple and very helpful method of pulse diagnosis. I highly recommend my colleagues to take this seminar. 
Thank you. Galina

Dear Igor,this is  to confirm I have received DVD, last friday. I saw your DVD on the method of the pulse diagnosis, it was most interesting. I would like to express mine gratitude for your good job. I study MTC since 1989, after a three-year course, in 1994 I obtained a diploma in acupuncture and mtc. I did not know this method of diagnosis, for me it was "enlightening".

I highly recommend the Wuxing pulse seminar as taught by Dr. Simonov. The information is presented very clearly and can be immediately applied as treatment strategies flow from the pulse findings. I run a fairly busy practice and was able to implement on a large scale what I learned at the seminar almost immediately after its completion. So far the clinical response has been very positive. I look forward to delving deeper into this method of pulse diagnosis and treatment and I thank Dr. Simonov for being so generous with his knowledge and time.
Thank you! Sasha
