勾(半边提):
歌诀：冲Punh Hold Arm Down Block; Swing Arm Bar Leg Hang; Hook Enemy Fall.
招势分解：
当Oppo. 迎战我，用Left Leg Kicks My Face Door。我闪避，用Left Foot Back Step,Bend Knee into a Low Horse Stance with my hands up in a guard position to block the kick. Then I use my right hand to deflect their left leg and hook it with my left foot. This leaves them off balance and vulnerable to attack.
The next step is for me to quickly move forward with both fists flying at them from different angles while they are still recovering from the previous attack. This will make it difficult for them to defend against all of the attacks simultaneously.
This style of fighting is called "Natural Gate" because it uses natural movements that flow together seamlessly like a gate opening and closing. It is also known as "Eight Trigrams" because each movement represents one of the eight trigrams found in ancient Chinese philosophy.
The goal of this style is not just to defeat your opponent but also to teach them something about themselves through your actions during the fight. By using these techniques you can demonstrate your skill without causing permanent harm or injury to your opponent.
In conclusion, Du Fei Hu's Natural Gate Eight Trigram Fist technique is an effective way for martial artists who want learn how best protect themselves while teaching others about their own strengths and weaknesses during combat situations by utilizing fluid motions that resemble those found within nature itself - hence its name 'Natural Gate'.
