In these clips I demonstrate Zhenjin (震劲), Shocking Power. The first clip showcases the main fist attacks, the second clip shows a modified form of the third fist used in dagger fighting and the third clip shows Master Zou Jianhua (邹建华) not even trying. This type of power can be used in most types of attacks! Enjoy!

Note: Sorry, I don't know how to link to the exact post and I usually don't put these types of low-quality clips on Youtube.
