After 6 months, the sand burn man stopped teaching. Sin Kwang heard about Grandmaster Ie's school and went to watch. Grandmaster Ie had 80 students practicing empty hand forms, weapons forms and sparring. The 7 year old Sin Kwang asked to join the school, but he was put off with polite excuses. One evening, Grandmaster Ie spilled a bowl of uncooked rice on the training hall floor. He asked Sin Kwang to pick up the rice, grain by grain, and to blow the dust of each grain. He was to find all of the 855 grains that had been in the bowl. It was late at night, and the Shaolin students had all gone home, by the time Sin Kwang was through dusting and counting the rice.

The rice counting was only the first of many tests of determination and character Sin Kwang passed. For the final test, Ie spilled hot tea on the boy and took hold of him, looking deep into his eyes. He saw no anger, only surprise. Sin Kwan Thé was finally accepted as a Shaolin student.

In the beginning, Grandmaster Ie had Sin Kwang do hundred of squats to build up his legs. They were done standing on the edge of a chair, with only the balls of his feet touching the seat. He also had Sin Kwang stand in horse stances for what seemed like an eternity. Next came mastering all 49 postures of the I Ching Ching. Only after these preliminaries were completed, did training in martial techniques begin.

Five years later at the age of 13, Sin Kwang Thé tested to Black Belt. For his test, he had to spar 7 other students while blindfolded. He also had to do forms blindfolded. At different times during the forms, boards were held in his path. Since he didn't know when there would be a board, every strike in every form had to be true.

In 1964, Master Sin was preparing to go to Germany to study engineering and physics. He had added German to the multitude of languages that he could speak. Yet the Berlin crisis altered his plans. By chance however, he met a couple from Lexington, Kentucky who were able to arrange a scholarship in the US for him. Master Sin Kwang Thé came to the United States.
