Sam's father was a doctor in the Chinese armed forces in the 1940's-50's and he arranged for Sam to receive instruction from high level military martial arts teachers including Lau Fat Mang (Eagle Claw), Han Xingyuan (Yiquan, Xingyiquan, Baguazhang), Yu Pengxi (Yiquan), Chang Dongshen (Shuaijiao), and Zhang Xiang Wu (Taijiquan, Xingyiquan, Baguazhang).
Seems he also was a student of Dr. chi chiang-tao tai chi who was student of CMC........
The book "Masters of Perception" is about his teachings and the last chapter of "The Tao of Yiquan" is devoted to his teachings ......
Enlightened Transmission
Master Tam began his teaching in the San Francisco Bay Area, but soon he was
conducting workshops and retreats in the United States, Europe, the Middle East
and Asia. As his reputation spread worldwide, it became his turn not only to carry
on the tradition of shifu, but also to become recognized as one of the world’s
greatest authorities on the internal martial arts.
As part and parcel of this reality, a steady and increasing stream of visitors from all
over the world has come knocking at his door, seeking individual training, instruction
and counseling. Many, if not most, of these visitors are already teachers of martial
arts and in fact come to Master Tam to learn his style with the intent of teaching it.
Though he has not sought out this recognition, the process has made Master Tam
a de facto “teacher of teachers.” In Chinese, there is a term for this: dashi (大師),
an honorific bestowed strictly on the basis of skill and actual achievement. Da
meaning “big” and “shi” meaning “teacher”, dashi (大師) literally means “Big
Teacher.” The dashi is a purveyor of enlightenment, sought out by other teachers
who desire to receive the deepest knowledge and acquire the most refined skills.
