Commentary

To start of with, the Muyo bone point and the Zhengdu point are two different and distinct points.
They are so close together most martial artists that study and practice pressure points do not know if they are striking Muyo or Zhengdu. I will clarify the difference by first discussing Muyo, the point on the grand masters chart, then the other point Zhengdu.

Muyo bone, is located on the inner tibia bone, about 7 cun (inches) from the top of the tibia and 6 cun from the bottom. It is one of my favorite stop action kick points which will totally halt an attack and leave your opponent at your mercy. That is what is meant by the term senselessness. The attacker will draw a neurological blank and be unable to move from that spot. There will be little to no further movement from the attacker other than a slight slump forwards from the waist up when the strike is performed correctly. The common weapons used for this strike can be several types of kicks, either with snap or a thrusting techniques. I myself have used it many times with a rear leg front ball kick out of a walking stance, or a spinning rear back kick using the heel. This stopped the opponent dead in his tracks, which gave a window of opportunity in which I could become like white on rice, if you know what I mean. I would use a ball type snap kick which would hit the center of the tibia and slide off to the inside of the tibia bone. That is one way to do it but almost any kicking weapon can work.

Zhengdu point, on the other hand, is found just behind the tibia in the muscle mass behind were Muyo bone is found which is on the bone itself. Muyo and Zhengdu are found at the same level but not in the same area.

Muyo and Zhengdu are similar as far as results. Muyo being the lesser of the two points. Zhengdu has a far more powerful result. Grand Master Soken, placed the Muyo bone and not the Zhengdu point on the second chart (given to Sho-Dan and above) but he did not give a special warning when he listed Muyo bone’s out come in his notations. I have found Muyo bone to be relatively safe, in most cases. So why would the Grand Master put it on his second chart in stead of his first chart (to the Kyu ranks)? Why would he put Muyo in the Dan chart and not Zhengdu when the Dan chart lists all the first level fatal strikes if Muyo is not that dangerous?

One reason is, In striking Muyo you can automatically strike Zhengdu at the same time and Zhengdu is a chi collection point. What does that mean? Here is where we get into one of the greatest mysteries in the pressure point arts. First of all, there is really no such thing as an energy drainage point! The Longman dictionary of American English states: Drainage is a system that carries waste away! A more clear term for drainage point maybe the term “energy storage point”. Yes you heard this correctly, to say it is an energy drainage point would be misleading. Simply because the point stores energy it doesn’t drain it! Any points, when damaged by heavy pressure literally become ill by losing or gaining to much or to little chi causing an energy imbalance in the point itself. All other areas of the body will give up some of there energy(Chi) to help the damage to heal or re-balance. Why? because there is a system of chi balance needed by the entire body at all times.

You may consider any pressure point strike, when it has been hit, to be like a country in which one of it s cities is having a black out. That city will get energy from another part of the country so that it will regain it’s power once again. If you understand what I am saying, when an electrical facility has a natural abundance of power it will sell its extra power to a needy facility. It is the same with all organs of the body. When any point is ill it will naturally take from all other organs within the body using the transportation highway called the meridians. Now if the point that is hit is a collector point it will steadily take energy from all other organs by way of the meridians and will cause those meridians ,organs and points to become imbalanced slightly. They will be effected in any case by a strike to any point even to the distant areas of the body. That means that all meridians and organs as well as skin and bones are all quite open at this point to a secondary attack. Now when the point is a collector, it will continually rob the other parts of the body, and those meridians and organs will be weakened by the collector which in this case is Zhengdu. It does not drain, it collects from the second point hit in a dramatic fashion! So that secondary point, is the point that is being drained, Not the first point hit which is the collector!

Collecting energy is a fact no matter what point is hit. But when it is a collector point the effects are multiplied dramatically. So in short when the collector is hit first it collects chi from all points and they all become weak. But the second point struck collects, automatically to supply the first, and all other points in the body feed into the second point and it will not stop collecting till the damage is repaired or the systems shuts down! This Factor is called the law of opposites, remember you heard it here first.

Now if Muyo is struck, the effect would be senselessness (only) for maybe a two second window. If the kick continues on to strike Zhengdu, (the collector) the window is extended for some time, until the body can re-balance itself and that will depend on the general health of the attacker.
Because Muyo and Zhengdu are on the lower part of the body and because Zhengdu is a Chi collector, a secondary strike that lands high on the body like to the head, neck or upper chest, does not have to follow the element chart to work!!!! This is just one application of the law of opposites which is, strike low than high, others are; high then low, strike right then left, strike front then back, and so on.

Also The element opposites for Zhengdu are, the lung and the large intestines meridians, But weather you are using the element opposites or not, the first two rules apply as well, if you were to use all of rules together, WOW, now we’re talking about deadly force.

Understanding these rules are the keys to the kingdom (so to speak). Understanding this law, makes point striking work. All the collector (points) are listed in almost any acupuncture text book, you may even find a text book in your local library.

Footnote: These laws and more can be seen in any Acupuncture manual. I have even found them in paperbacks in my area Library. One great text book which you can look into is named, Chinese Acupuncture and Moxibustion. The term “ENERGY DRAINAGE POINT”, IN MY OPINION, IS INCORRECT ,although the term is used world wide. Also the kicks are demo-ed in the Nahanchi , Chinto kata, and in many soft art forms.
