关于强力发劲与轻微抚摸。About exerting strong power or lightly stroking

Gently moving on the opponent's skin, it may seem that it is not enough to move a body weighing more than 100 pounds. However, it will definitely force the opponent to make adjustments to balance. The opponent's imbalance is not due to my strength, but because he has not mastered the method of adjusting his own balance. If you do not understand this principle, you will never understand the mechanism of Tai Chi's use of softness to overcome hardness. You will not be able to enter the door of Tai Chi.
We are not necessary to use force to move the opponent, but gently stroking his skin moved his body lightly. In fact, the power exerted by those Fa Jin masters is also not enough to move the hundreds of pounds of the opponent's body. We can say that even under strong attack force, The opponent's stiffness still is the main reason why he can be knocked down.
So, why we do not try to use less force. Why some people were proud of themself because they should use more force. Martial arts are not about explosive power, but a way to defeat the opponents.
However, this gentle stroking must be based on good listening Jin skills and self-balance skills. Otherwise, it will be impossible to achieve "neither against nor escape" principle and it could not be smothered and no break point movement, therefor it will be difficult to see ideal effect.
Tai Chi push hand is just one of the important means of exercising skills and not all. People should understand in advance, you can't strike with your hands, or kick or trip your opponent. Therefore, some people accuse the push hand of having no actual combat effect, and by extension, saying that Tai Chi has no actual combat effect. That's a misconception. It should be said that the push hand has the function of "actual combat", but it is only known that the push hand is not enough to meet all the needs of "actual combat“.
