The Empty Leg, The Full Leg

After reading one article by Dong Ying Jie a few weeks ago, I started thinking about this 虚实, empty and full thing. I think I have got something, but still not everything.......

In every movement, be clear where is empty and where is full.

I realised this is very important, especially in transition movements.

The thing is when you are stretching out your leg to take the step,

is your leg stiff and full?

Or is it empty and pliable?

When you first put your feet down, before you transfer your weight over, is your leg stiff and hard?

Or is it soft and pliable?

When you transfer your weight over, is it quick?

Is it smooth?

Does your leg immediately shift from empty to full?

Your intention shift from leg to leg?

Did you leave anything behind?

Was there reluctance in your movement?

Was the transfer just nice?

Did you go overboard?
