The Lan Sau or bar arm, is a lifting block / bridging technique. It looks similar to the Bong Sau but unlike the Bong Sau the arm forearm is level with the shoulders and more or less parallel to the body and the rotation in the forearm is up not across.
In the Forms:
There are several occurrences including in the Chum Kiu Form and in the Muk Yan Jong Form.
Application:
Best performed to a straight punch then with a Lap Sau and an elbow break, as seen in the second form. (lineage dependant).
