Note: The below are general concepts of Chi Sau and is not a means to teach or a complete guide.
Chi Sau is used by students as a training tool to train different aspects of the Wing Chun system.
Chi Sau is performed with two people facing each other, each person in Yee Gee Kim Yeung Ma (二字拑羊馬) – Wing Chun Stance.
Primary objective of Chi Sau is your Yee Gee Kim Yeung Ma (二字拑羊馬). Students need to understand and detail (evolve) their own Yee Gee Kim Yeung Ma when in contact with another person in Chi Sau.
It is also used to teach about
- that the Yee Gee Kim Yeung Ma is one structure
- the arms and hands are independent of the Yee Gee Kim Yeung Ma
- sensitivity of your forearms, hands and your stance when in contact with another person
- distance, range and target between you and the other person
Daan Chi Sau (單黐手) – Single Sticking Hands
- learn what is inside hand (inside gate), what is outside hand (outside gate)
- learn about the four faces of the forearm
- training the sensitivity of the four faces of the forearm
Each person will have only one forearm performing the Chi Sau (黐手) thus the name Daan Chi Sau (單黐手). The other forearm will be at the side holding a fist (拳).
One person performs the inside hand (inside gate), one at a time as below and is repeated:
- Taan Sau (攤手)
- Churn Sau (正手)
- Bong Sau (膀手)
Note: Taan Sau can turn into Churn Sau or Bong Sau. But Bong Sau can only turn into Taan Sau.
The other person performs the outside hand (outside gate), one at a time as below and is repeated:
- Fook Sau (伏手)
- Wu Sau (護手)
- Yat Ji Kuen (日字拳)
Note: Fook Sau can turn into Wu Sau or Yat Ji Kuen, Wu Sau can turn into Fook Sau or Yat Ji Kuen and Yat Ji Kuen can turn into Fook Sau or Wu Sau.
Seong Chi Sau (雙黐手) – Double Sticking Hands
Each person will have one forearm as an inside hand and the other forearm as an outside hand:
- Both person will have an outside hand as a Fook Sau (伏手). Thus if the right hand is a Fook Sau, both persons’ right hand will be a Fook Sau.
- The inside hand will either be a Bong Sau (膀手) or a Taan Sau (攤手). If one person’s hand has a Bong Sau, the other person’s hand will be a Taan Sau.
Luk Sau (碌手) – Rolling Hand
Sifu Derek Fung uses a coat hanger (衣架) as reference to teach for many years.
It is a rule that whoever has the Bong Sau will start to Luk Sau (碌手) first when that person is ready when two people are doing Chi Sau. The momentum of the Bong Sau will force the opposite forearm, Fook Sau to Luk Sau.
In Chi Sau, one person or sometimes both persons can sense/feel a gap in either one or both forearms/hands when doing Luk Sau (碌手). With that gap, either person or both persons has that split second to change that inside hand/outside hand to an outside hand/inside hand but never changing both hands at the same time. This is called Jou Sau (走手) – Running Hand. This is learnt by advance students in Chi Sau.
