Cha Jee Sau
Introduced during the opening sequence of Siu Lim Tau, this cross-armed block is used to mark the centerline from extreme low to extreme high. It can also be used as a reference point for defining the gates.
Performing Cha Jee Sau:
Extend the arms simultaneously outward and down, ending where the arms are crossed at the wrists in front of the Dan Tien. The left hand will be on top of the right. Bending the elbows, bring the arms up while simultaneously turning the hands over so they end palm up. The arms remain crossed at the wrist throughout the motion. In the final position, the wrists are crossed just slightly above the horizontal line of sight, again with the left wrist on top of the right.
Cha Jee Sau as a Block:
The crossed-arm structure – technically a double Gahn Sau – can be used as an emergency block against a powerful rising attack. An example would be where your structure has been compromised by a Muay Thai-style head clinch and you must block a knee or kick to the body.
