In my childhood I boxed, practiced Taekwondo, and then practiced Kyokushinkai Karate for five years.

Since 1991 I have been practicing Wing Chun, and since 1999 I have been a Si Fu (master).

From various masters I have learned the branches of
• Ji Sin Wing Chun (Chi Shim Wing Chun)
• Lok Yiu Wing Chun
• Lo Man Kam Wing Chun

Since the 1980s I have been practicing Qigong (Chinese energy exercises), and since the 1990s I have also been teaching it.
In addition to classical Chinese weapons, I have learned knife usage and Arnis short stick techniques from various masters.
Alongside traditional martial arts, I have learned various police and military close combat techniques at seminars and privately.

I have been teaching martial arts for more than two decades, several of my martial arts books have been published or are in the process of publication,
between 1997 and 2002 I was the editor and editor-in-chief of the KUNG-FU newspaper, and since 2011 I have been the editor-in-chief of its successor, the KUNG-FU Online Magazine.
