He is seen spreading a mat on the floor and measuring out the rice with which he intends to pay Ah-jung (aka "Rice Cake Girl").

Since the film does not offer an explanation, it's up to each viewer to decide which scenario makes the most sense to them.

She calls it "a meridian point that can loosen the knots in your heart and clear all the horrible memories from your mind."
