Master Sam FS Chin applies a Chin Na 擒拿 application, commonly referred to as a "small wrist wrap" in Chinese martial arts, or Nikkyo in the Japanese martial arts.

Master Sam FS Chin calls I Liq Chuan's approach to chin na "a flowing process".  Rather than learning set techniques, students are taught when and how to grab and when to let go based on the feel at the point of contact.

Master Chin has often said "We're not going to learn technique (of grabbing and joint locking).  The technique is already fixed, there's nothing more to learn there.  The important thing is the way into that technique" (i.e. recognizing the opportunity to grab and apply qin na, or joint locking).
