In the Chum Kiu form, the student is formally introduced to the concept of stance turning and a variety of combination stance work exercises based on the five Moving Stances taught at the previous level. He or she is also instructed in greater detail about the Centre line Theory as pertains to the horizontal Elbow-Level Mother line, Blocking and attacking Lines. The eyes are trained in Chum Kiu to focus quickly and there is more emphasis on the development of power, both externally in the form of torque as well as internally through learning to flow the Chi, or Internal Energy, smoothly to various parts of the body.
At this level, training in important drills such as Lop Sau, Mun Sau and Syeung Chee Sau - Double Sticky Hands begins. The concept of timing one's movements in relation to an opponents studied in detail. Trapping Hands of many types are drilled and sharpened by Chum Kiu-level practitioners in the "Slow Attack" exercises. Pyramid concepts and Yum/Yeung (Yin/Yang) theories are analyzed and discussed in a classroom atmosphere, with the instructor serving as lecturer,assuring that all students have a thorough intellectual understanding of the logic behind these and other Wing Chun concepts. During such discussions, the instructor will use a blackboard to explain some of the theory, but might also use objects as varied as a ball of cotton, a tack or nail, a serving dish, an opening and closing door or other such unlikely items to help illustrate different points. This is no coincidence. By Chum Kiu level, the Wing Chun student is able to see that all the workings of the system are clearly based on logical, tangible facts and principles which apply equally to many everyday objects, occurrences and situations.
The student at Chum Kiu level is also trained in some of the kicking techniques of the system, which are characterized by their shortness and speed. Wing Chun kicks rarely go above waist-level and never above chest-level. This is due to the economical structure of the system and the inherent danger of raising the foot during combat, an action which automatically temporarily immobilizes the kicker. Wing Chun kicks can be executed with a block, strike or trap, or a combination of any two. To develop this skill, the student is instructed to practice some of the drills taught earlier with kicks inserted at strategic points in the repetitive drilling cycle.
