Accupressure point touched during the preparation posture

[TaiChiTJ]

I was looking through the instructions of the form (37 posture) on the Huang Sheng Shyan site and they mentioned an meridian point on the thigh during preparation posture:

立正预备：
lì zhèng yù bèi:
Stand to attention: Stand to attention, heels close together (not touching), knees slightly bent, both
hands on side of thighs with middle finger touching Feng Shi point.

something I was not aware of.

 

[Xue Sheng]

You get the same thing in the beginning (wuji) posture of Sun Style Taijiquan. I have not seen it in Traditional Yang, CMC, Chen or Wu that I trained.
