Another defining point of Bak Mei kicks is that they are hidden, meaning that the kick is either masked behind a feint/deception or a hand strike to distract away from the kick. A loose analogy would be that the kick is like the snake in which the strike is fast and that there is no warning.
The areas to strike with the kick in Bak Mei are usually focused on the legs, knees, groin, and abdomen.
Some signature Bak Mei kicks include daang gek (nailing kick), tek sa gek (sand flicking kick/groin kick), and chuun sum gek (piercing heart kick).
Food for thought: "A kick to the head is like a punch to the foot"
