According to the short video platform of vibrato, boxing is a traditional family-run boxing, which originated from boxing in Song Dynasty and developed to Duan's Yin-Yang Finger in Ming Dynasty and martial arts boxing in Qing Dynasty. It is a kind of kungfu that integrates fighting, acupuncture, fitness, health preservation and fitness. Duan is the 14th generation descendant of Boxing, and also a martial arts health preserving family. He studied boxing with his father Duan since childhood, and later studied under famous teachers such as Zhang and Han Dongyue. He was proficient in 21-point kungfu and 21-skill health preservation. Duan has an account named "Two Instruments Section" on the website, where she often posts some videos about two instruments boxing and acupuncture to show her martial arts skills and cultural background. Duan's acupuncture technique is true. She has performed on many occasions and in the media. Many people have personally experienced her acupuncture skills and are very surprised and admired. Segmental acupuncture is based on the principle of meridians and yin-yang theory of traditional Chinese medicine, which uses internal qi and finger strength to stimulate or close human acupuncture points, thus achieving the purpose of defeating the enemy or treating diseases. To sum up, I think I can answer your question: Duan's two fists are true. She is a martial artist and scholar with real kungfu and inheritance. Her acupuncture kungfu has scientific basis and has been proved by practice.
