Bak Mei is known for it's power generation via luk ging, sei ngoi ging, and baat ging so I've decided to make a video breaking down a simple technique to showcase words to action.
Our focus will be the Arrow punch (Jin Choi). It is called Jin Choi for the fact that the stance looks like an archer holding a bow preparing to loose an arrow.
The power of the arrow punch comes from the turning of the hip verses just utilizing the shoulders as you would in a boxing jab. the fact that you are perpendicular to the opponent when the punch hits allows you to twist your hips to facilitate the torque to the strike therefore increasing the power of the "jab".
As always, actions speak louder that words. Enjoy the video.

Addendum
Further to the subject of power generation as it pertains to this arrow punch as a "power jab", I've been recently asked by some students the differences in ging (power). I will start off by first differentiating between strength (lik) and power (ging). Simply put muscular strength is blunt and dull while developed power is sudden and sharp.
ie. punching with shoulder vs punching with the waist/hips.
Bak Mei Ging (Power) is classified into the following:
LUK GING (6 sectors of kinetic bridging) aka kinetic chain of biomechanics:
They are gek, yiu, bok, sau, geng, and nga (legs/stance, shoulders, arms, neck, and teeth). This means that all these parts must be coordinated & integrated to allow proper force emission.
SEI NGOI GING (4 internal dynamic forces) / kinetics:
ie. fau, chum, tun, tou (float, sink, swallow, spit).
This refers to how power should be produced and exerted.
BAAT GING (8 manifestations of force) / Kinematics.
This refers to when luk ging and sei noi ging are properly performed and is given proper direction.
They are: bin, got, waan, jong, chung, taan, sok, and pun (whip, cut, pull. crash, rush/charge, flick/bounce, rope, and coil.
As you can see there is much more to Bak Mei than just the external motions. It takes time to become proficient at each level before you can move forward. Meaning that you must understand proper alignment (luk ging), before you can properly practice sei ging. Luk ging and Sei ngoi ging must be understood and properly performed before you can execute baat ging.
