Master Ong had a picture of Master Lao that he showed to Master Wasil. Master Lao was a very big man and was distinguished looking with a mustache. Master Wasil judged his age in the picture to be about 48 years old. Master Ong told him Master Lao was over 90 when the picture was taken.
Master Lao Pei-zhong's main concentration was on the internal side of the art and was very skilled in meditation. He never slept. He didn't need to. Instead he would meditate for somewhere between 4 and 6 hours a night to rejuvenate himself. Even so, he had so much power that he could walk through a door without opening it, and without giving it a second thought.
Master Lao also had a deep appreciation of the philosophy of the art. He wrote the small booklet "Goodness Creates Happiness" which gives valuable guidance on how to live our life in an upright and moral way.
