Wan Kam Leung Practical Wing Chun NJ


Sifu Eric Chirlin (莊力亞)

Head Instructor


Sifu Eric Chirlin began studying Wan Kam Leung Practical Wing Chun under Sifu William Kwok in New York City beginning 2011. Sifu Chirlin found an immediate appreciation for the simplicity and depth of Practical Wing Chun and its concepts, and for the focus on traditional Chinese and martial arts culture that Sifu Kwok encourages in his students.

In 2012, Sifu Chirlin joined Sifu Kwok’s specialized Instructor Training Program, designed to provide experienced students with in-depth educational training including curriculum design, motor learning, and teaching methods, as well as a deeper understanding of Practical Wing Chun. Since then, Sifu Chirlin has traveled to Los Angeles, Las Vegas, and Hong Kong to train personally with his Sigung, Grandmaster Wan Kam Leung, and to assist Grandmaster Wan and Sifu Kwok in conducting seminars for martial arts enthusiasts from all over the world. Sifu Chirlin became a second-generation inner disciple to William Kwok in a traditional Bai Si ceremony in May 2017.

Sifu Eric Chirlin holds a Bachelor’s Degree in Computer Engineering from Stevens Institute of Technology and studied at Queen Mary University of London in 2010. As a New Jersey native, resident of Jersey City, and professional in New York City, he aims to use the teaching of Practical Wing Chun in Jersey City to share his understanding of eastern and western culture and philosophy, and ultimately help practitioners find balance in a fast-paced and disharmonious environment.


Sifu Yvonne Kwok (郭欣融)

Program Director


Under her brother, Sifu William Kwok’s guidance, Sifu Yvonne Kwok began her training in Hong Kong at the Practical Wing Chun Headquarters with Grandmaster WAN Kam Leung, founder of the system in 2005. She continued her practice with Sifu William Kwok after she moved to New York City in 2006. Sifu Yvonne Kwok has assisted Sifu William Kwok to develop the Practical Wing Chun program in New York City, the first American branch; she was also an original member of the Instructor Training Program (ITP), a program developed by Sifu William Kwok to educate instructors to thoroughly understand and apply the Practical Wing Chun theories as well as teaching and class managing skills. Sifu Yvonne Kwok is the first official female instructor of the Practical Wing Chun system in North America.

Sifu Yvonne Kwok is blessed to be inducted by Grandmaster WAN Kam Leung as his 3rd generation closed door disciple in May 2013, she is one of the two female closed door disciples of Grandmaster Wan. She truly believes in the system and sees its potential to expand and grow so more people can benefit from it. To her, Practical Wing Chun is more than a martial art; it is a bridge that connects her with her cultural roots and her identity. As a Hong Kong native, Practical Wing Chun offers a channel for her to share her passions in Chinese art and culture in the West.

Besides Practical Wing Chun, Sifu Yvonne Kwok has over 13 years of Taekwon-Do experience and will be pursuing her 4th degree black belt in 2018. She has been teaching Taekwon-Do for over 10 years and she is the Head Instructor of the Children’s program of Gotham Martial Arts. As a female martial art practitioner, one of her goals is to promote the merits of martial arts training to women; she has developed a Women’s Self Defense and Fitness program as she hopes to empower women and help them build sense of awareness and confidence.
