Master Sit began his study of the martial arts in 1968, at the age of 18. He began his studies with Karate, then changed to Taijiquan, southern Gong Fu and other styles of martial arts. He specializes in Wu Taijiquan, Six Elbows (southern) Gong Fu and a rare internal style called Tai Hui, of which he is the only instructor in the entire USA. He also practices Bagua and Chen Taijiquan "just for fun".
When asked by one of his students why he decided to study the martial arts, Master Sit replied,
Why do American kids play baseball? They play because it's a part of their culture; I practice martial arts for the same reason.
He enjoys teaching workshops and judging at major Taijiquan and Gong Fu competitions. He contributes articles regularly to Tai Chi Magazine, and is currently writing a book about "Quantum Taijiquan". In it he incorporates his favorite teaching methods which combine modern physics with the Taijiquan Classics, Tao Te Ching, and Buddhism.
