Axe Chopping Principle

In this week’s SKD I delved into the principle of axe chopping to deliver a strike.

Interestingly, in a non-mainstream Wing Chun that I learned we have a punch called Tup Chui which is literally Hammering Punch in which the punch is not straight out but delivered in a downward curving manner. My final Wing Chun teacher also punched in this manner and he is able to punch really fast and powerfully using this process.

I had also encountered this way of punching in the Biu Jee form of the Ip Man style when my senior taught me this version from one of Ip Man’s lesser known disciple. This punch is performed at the end of every section.

The video below is an introduction :-

Here is where I mentioned the axe chopping in relation to Xingyi’s Pi Quan :-

In SKD this is how we use arm swinging to develop the chopping power :-

To be able to apply the chopping strike we use Tai Chi principles to learn how to relax and control our arm and body acting in concert to deliver the strike.

The arm-whole body movement is my adaptation of Grandmaster Wei Shuren’s Step Back Repulse Monkey from his 22-form. The arm rolling into backfist movement is the final movement in Repulse Monkey.

2021 Day 2

It started to rain last night.

It kept on raining throughout the day. I woke up to a dark, cold and gloomy day.

Practicing Tai Chi is a good day to get the blood circulating. Some say to circulate the Chi.

Playing the Tai Chi form is a good way to train your ability to concentrate, develop awareness of how your body is moving in response to your mind.

When you can quiet down your mind you can focus so much better. In this way you can reduce the outer movements, concealing the movements that are happening inside your body. This is what we mean by being internal.

Good control of the body allows you to tread like a cat. At the same time your body is moving like a series of gears to rotate and spiral to connect to the ground to generate power.

While it does not seem like it but within the slow, seemingly gentle movements we are working the power generation process.

Resolving Double Weightedness

One of the topics from our SKD online lesson on 11 Jul 2020 is on the importance of not being double weighted.

In this clip you can see the principles of Tai Chi at play in SKD to solve the problem of double weightedness.

In this instance, I am explaining the application of the “2 4 points” in the use of footwork to illustrate why it is important to avoid double weightedness as it affects our ability to move.

Song of Chaos


What I like about Grandmaster Wei Shuren’s Yang style is its clearcut learning map. In some Yang styles they seem to have too many types of jing or unclear if not confusing learning roadmaps.

For example, I saw a very nice graphic recently outlining the different types of power. The author divided the types of power into :-

a) Structural Power (internal strength)

b) Elastic Power (elastic store and release)

c) Peng Power (internal pressure)

d) Ground Power (ground reaction force)

However, I am a bit confused here because aren’t the 4 powers basically parts of the same type of power?

This is the logic of my analysis :-

i) You first have a body structure. In our Tai Chi we use the Bell Body structure.

ii) When you stand upright your Bell Body structure is connected to the ground.

Note – A characteristic of the Bell Body is inflation of the body like an elastic ball; what we call Peng Zhang (膨胀) as opposed to Peng Jing (弸勁). It is my opinion that Peng Zhang is frequently confused for Peng Jing. Peng Zhang is a quality whereas Peng Jing is a force vector as shown below :-

iii) Your body structure pressing against the ground with the help of gravity leads to ground reaction force as per Newton’s 3rd Law of Motion which states that for every action, there is an equal and opposite reaction.

iv) That your body is opened up means that the body’s 5 bows can be accessed. This allows you to borrow, store and release the opponent’s strength like releasing an arrow. The process here is just converting potential energy to kinetic energy, basically a type of elastic power.

v) Lastly, the characteristic of Peng Zhang (膨胀) means that the body is rounded. If so, then we can access Peng Jing (弸勁) which is a type of circular force vector.

In conclusion, by using one body structure, Bell Body, we have the 4 types of power mentioned by the author!


In Grandmaster Wei Shuren’s Tai Chi we approach the topic of force differently.

There are many ways to apply force in our Tai Chi. GM Wei’s book on the 22-form has many models of how to apply force. Sometimes I think far too many.

Sure, it makes for fun learning. Tickles the grey cells even. However, for application I feel that you only need something more straightforward, something you can use easily without having to think very hard, something you can pull off even as the opponent is trying to hit you back.

Fortunately, in Grandmaster Wang Yongquan’s book there is a Song of Chaos which he penned based on his practice insights. Note – the book was actually written by Grandmaster Wei but published under GM Wang’s name with his approval. The Song of Chaos is as follows :-









I once asked my teacher to explain the above to me. The moment I heard his explanation I realized how important it is to thoroughly master all the requirements of the 22-form.

This is because the 22-form (or for that matter the 37-form, the 108-form and the 8-step Health Form) is configured to provide the necessary practice for acquiring the physical understanding to actualize the skills outlined in the Song of Chaos.

Why Emptiness

In today’s post I touched a bit on the training of emptiness.

The training of emptiness is actually simple and straightforward. But it can be maddeningly difficult to catch like trying to grasp water.

I guess this is where the fun of learning is. And when you get there it can be incredibly satisfying because you have something that most Tai Chi practitioners will never understand much less be able to acquire.

You will be able to have a glimmer of understanding why the first two generations of Yang family, Yang Luchan and Yang Chienhou, were said to have high level skill.


This CB lockdown has one good thing going for me – time to practice in the morning before I start work at home.

For some reason, I think it is the way I have to focus on the tons of fine details that is embedded in the Tai Chi form as I move through it, that clears up the mind and help to perceive things more clearly.

Sometimes too clear a thinking is bad, cause I end up writing a post like “WTF” here.

Hand Shapes Training

One topic that is not addressed enough in Tai Chi training is the use of hand shapes.

This topic is part and parcel of our training of Grandmaster Wei Shuren’s Tai Chi.

In the training of 8-step Health Form I am addressing this topic here by explaining how to train the hand shape to issue power.

The video below is a demonstration of the use of the palm hand shape :-
