[7][8] Prior to learning Practical Wing Chun from Wan Kam-leung, Kwok trained in various martial arts systems including traditional Taekwondo, under Kim Suk-jun, a disciple of Choi Hong-hi.

Wing Chun Illustrated writes: "Like the famous monk Xuanzang in the classic Chinese novel Journey to the West, who journeyed to India in quest of the Buddhist scriptures, Kwok helps bring Practical Wing Chun to America, teaching Westerners how to understand and decode this ancient, yet still modern, Gung Fu style.

[12] In September 2017, he was invited as a guest presenter at the first Wong Shun-leung Ving Tsun North America seminar in Los Angeles, California.

[20] Before promoting martial arts education in America, he taught business studies as an adjunct professor at City University of New York.

[26] Kwok founded and acts as president of Martial Arts Education Society in 2018 with the mission of “bringing self-discipline and hope back to our communities."

[30][31] Kwok's self-defense philosophy highlights the significance of sensory perception and body language as essential skills that empower individuals to take control of their safety.
