"Repulse Monkey" is an excellent technique against the Muay Thai knee jabs

Just as you do not block a knee jab of a Muay Thai fighter head-on but deflect it using "Needle at Sea Bottom", you also do not jerk away his grip on your neck with brute force. You can gently release his grip with an upward threading-hand, using the pattern "Lift Hand". Then fell him onto the ground with "Repulse Monkey", and finish him with a decisive strike.
