What is the meaning of bump energy?
Its method is divided into the shoulder and back technique.
In slant flying posture use shoulder,
but within the shoulder technique
there is also some use of the back.
Once you have the opportunity and can take advantage of the posture,
the technique explodes like pounding a pestle.
Carefully maintain your own centre of gravity.
Those who lose it will have no achievement.
(Tan Meng-hsien)
