I once punched the sandbag during my Shaolin training.

I took the Wing Chun front stance, And I started to punch
*Boom* It only moved for a little.

I then give the sandbag a chain punch
*Boom* *Boom* *Boom* *Boom* *Boom* *Boom* *Boom* *Boom* *Boom* *Boom* *Boom* *Boom* *Boom* *Boom*

The sandbag only moved a little, seems like I didn’t use my energy. But I used Fa Jing, and Chi, to punch it!

My friends are laughing at me, They said my punch had no power. One of them also tried to punch the sandbag, He did learn a little boxing, so his punch made the sandbag moved much more than what I did…

However….

When I encounter a fight, I use the Wing Chun punch. I used 25% of my effort compared when I punched the sandbag, while my opponent had been finished. He got injured. I escaped successfully…

The Wing Chun punch is weak (If you punch a sandbag) but DEALS a LOT of damage when it was used to strike someone.

Similar to a slingshot… If you shoot the sandbag with it, you won’t make the sandbag move at all, But when you shoot humans, you’re going to be sued for assault…
