The strength of the roots and the power of heaven

In this video the Master Flavio Daniele shows us the incredible potential that can give the Nei Gong.
As you can see, the Master remains in perfect balance by placing only the balls of your feet on a narrow base of wood, resisting decided thrusts of a student without losing its central axis but not only, unable even to express a huge force only directing ... of a finger!
The video presented here belongs to Volume 8 of its work to the test Nei Gong.
Good vision!
