 So here's the eight types of Wing Chun energy. So energy number eight is called Ting Geng, which means listening energy. And you might be confused like, what energy is there in listening to something? Well, let me demonstrate. So Wing Chun martial arts, when we're listening, we're not actually listening with our ears, we're listening with our skin. That's right, you're listening with your skin. Just like if you are standing in front of a fan, if you close your eyes, you can feel the wind blowing on your skin. And if you listen with your skin, you can feel which direction the wind is blowing. You can feel how strong that wind is blowing.
