Adhering and Continuously Following; neither Abandoning nor Resisting
Master Chen said, “To harmonize (合住) means to equalize the force of your opponents. To be accurate you should maintain 49% force against opponents 51% and let the opponent’s force be felt on you. What if he did not manifest his force? Then you have to apply force on the opponent to evoke a counter force from him. Once the force and counter force harmonizes you must not move by maintaining the posture.
If he releases, you still must maintain the 51:49 force ratio. This called not abandoning (丢). If the opponent increases his force, you still maintain the same ratio; this is called not resisting (顶). From the beginning till end harmonizing his force at 51:49% ratio is called adhering, sticking and continuously following. It does not mean just maintaining contact continuously. When you have the harmonizing force at 51:49 you form a relation from the contact point to the opponent’s center. When you control the contact point, you control his center.”
