Park has been teaching boxing for three years, but no one cares about him. Until a top internet celebrity led a team to fight against counterfeiting. They kicked over my wooden mannequin in front of the entire Internet camera and sneered: "Does a flower stand deserve to be called a Chinese martial art?" I silently unbuttoned my shirt, revealing old wounds all over my body. They didn't know that this young man known as "Master Zhou" was once the Wing Chun killer in the dark boxing world, and he penetrated the golden belt of the Seventeenth Kingdom with one finger. From gymnastics live broadcasts to international competitions, when top fighters begged for defeat, and military special forces came to learn from him, the whole world understood that what he taught was not boxing, but the mercy of killing skills.
