hi
i have noticed that martial art like xing yi ,yichuan , white crane use gougua (hooking the hand ) and fali explosive energy
it s a system that hurt and very efficiency in real situation (it s very often that yichuan masters show their skills without any connivance with the opponent)
and in taiji
the empty power is a trap for making the opponent beleave that there is a resistance , a force but when he tries there is nothing so he s like aspirated by the void or emptyness. taiji play with the balance of the opponent
it s like like yangchengyu said trying to walk on the sea using watermelon
you are lost and have no balance
bagua may also use this empty power?
somy question is : is there two family of neijia one using grapping hand and explosive form and the other empty force like a trapp?
because in yichuan there is no play no technic to use the balance of the opponent.
