How did Deng Feihu aim at the slingshot?

1. Hold the slingshot obliquely, the included angle with the horizontal line is about 40~45 degrees, and the back of the hand holding the bag is just at the side temple of the aiming eye (as close as possible to the aiming eye).

2. Adjust the index finger and thumb of the bow arm so that the two rubber bands appear to recombine into a line in the aiming eye (it is the same reason that the upper and lower rubber bands overlap when aiming horizontally! )

3. Look forward along the rubber band near your face, adjust your forehand so that the end of this rubber band just covers the target center, and then fire!
