First, read the English article below.

The face is another highly vulnerable place to attack. Hurting your opponent's eyes, nose, and face can be a great way to cause great pain and to slow down your opponent tremendously. Here are some methods to try:  Headbutt your opponent's face. Use your forehead to slam your opponent across their nose. This can break their nose if you do it the right way. Poke their eyes with your fingers. This can cause excruciating pain and can blind and disorient your opponent for enough time for you to escape or cause more damage. Punch them in the nose. This is a highly effective place to cause some serious damage. Hitting your opponent's neck and face is guaranteed to stop them cold, if only for a short period of time. If you really want to cause some harm, try these indelicate moves:  Punch your opponent in the back of the neck to make them blackout temporarily. Punch your opponent in the middle of their throat to cause damage to his airway. If there are no rules in your fight, then your only goal should be to win. If you just want to win a fight, then you don't have to follow Fighting Etiquette 101 -- just try to get your opponent to be hurt, crippled, or to fall to the ground, giving you enough time to get away. Here are some ways to do it: Knee your opponent in the groin. This is guaranteed to stop them in their tracks.
