Come on, there got to be some changes.
If I am correct, long time ago when you do the Tai-Chi Wu-Chi pose (Chinese Horse stand), we try to lower our body as much as we can. Now, we focus on Safety first, with knee towards toes and straight back. So, some old poses are obselete.
Isn't this similar to Cobra, which legs are together or hip-width apart?
