Gong Bu (弓步）
Translated as "bow stance", Gong Bu is also known as "Deng Shan Bu" (mountain-climbing stance) or "Gong Jian Bu" (bow and arrow stance). The lead foot is pointed straight ahead, with the lead leg bent slightly. The trailing foot is angled outward at a 45 degree angle, with the heel lined up with the heel of the leading foot. The trailing leg can be held straight or slightly bent. The result is a "lunging" pose. In southern styles, the toe is if it had stayed in Ma Bu; starting in Ma Bu, the hind leg steps forward and turns while the front leg stays in the same position. In northern styles, the toe points forward. The given weighting is 70% on the front foot and 30% on the rear.
In application, it is popularly used for attacking. The structure of the stance partially protects the groin and allows the martial artist to punch with greater power by driving the rear leg into the ground. Additionally, the rear leg can be quickly drawn forward for kicking attacks.
