 Here's some reasons why Buji or spearhand is so effective. The first reason is targeting. We want to use the Buji to attack the eyes, which are very sensitive. It doesn't matter how much you lift weights, you can't make your eyes stronger, right? So we can attack the eyes, it doesn't matter how strong he is, how big he is, everybody's eyes are weak and especially if you have strong fingers, it will definitely devastate your opponent.
