Asian people are better at Kung Fu than Caucasians because Asians are consciously raised by their parents on Kung Fu principles from the time they are a baby. By the time they reach an age to begin the practice of Kung Fu, their body has already been trained in and changed by the basics of Kung Fu.
The posture of the child in this picture demonstrates just how young Asian children are when they begin behaving in a way that is a sign of development of the body according to Kung Fu principles.
In contrast most Caucasians know nothing about Kung Fu principles until they decide to begin Kung Fu training, which would usually be sometime in their teenage years. That means the average Asian is going to have a 15 year head start on the average Caucasian in a class teaching Kung Fu. And nothing can ever change that advantage. The Caucasian cannot go back in time to when they were a baby and begin training Kung Fu principles. The Caucasian is always going to be 15 years behind the Asian for their entire lives.
The training disparity only gets worse the older the Caucasian is before they begin Kung Fu training. If a Caucasian did not begin Kung Fu training until they were 25, that would make them permanently 25 years behind an Asian training in Kung Fu.
The point in knowing this fact of reality is to help the possibly frustrated Caucasian individual who does not understand why their Asian classmates seem to either do so much better in class, or learn so much faster. They have an advantage the average Caucasian person is never going to be able to surpass because of the way Kung Fu works.
A Caucasian person cannot decide to train 24 hours a day to catch up to the Asian student. Kung Fu development of the body does not work that way. Kung Fu development of the body is about slow and steady development over time. If someone has more time into the proper practice of Kung Fu, another person who has less time will never be able to catch up to them.
