Does mysterious acupoint Kung Fu really exist?

（ECNS）-- In Chinese costume dramas, people often see a miraculous martial arts skill called Dian Xue (acupoint), which uses pressure points to control or immobilize an opponent. Dian means to strike with a finger and Xue means an acupuncture point.

During fights, martial arts experts use their two fingers to swiftly and forcefully press on a certain part of the opponent's body, immediately immobilizing them.

Compared to Dian Xue, the Yijin Jing in martial arts novels is even more miraculous. Yi Jin Jing is known as a classic book about Muscle and Tendon Changing. “Yi” means to change, “Jin” means tendons and muscles, and “Jing”, methods.

Legend has it that anyone who masters the skills in this book can become a master of martial arts and even save others' lives, so martial artists eagerly pursue it.

According to legend, credit for Yijin Jing's development is given to Da Mo (Bodhidharma), an Indian monk who lived in the Song Mountains in central China.

Legend said that Yi Jin Jing was left behind by Bodhidharma after he departed the Shaolin Temple. However, there is some debate about the true origin.

But Zhou Weiliang, professor at Hangzhou Normal University, believes that in reality, Dian Xue and Yijin Jing are not as mysterious as they are portrayed in television dramas.

Yi Jin Jing includes the Dao Yin exercises and martial arts exercises. It emphasizes that the core of martial arts lies in internal strength, which is manifested from the inside out. There are no specific martial arts movements in the book. It mainly introduces some exercises to cultivate inner strength. The Dao Yin exercises are related to health preservation via meditation and practicing breathing.

In Qing Dynasty(1636 -1911), some stories mentioned the book Yij Jin Jing. Zhou said that many Qing Dynasty notes are similar to novels, and recorded events are more like stories, in which Yi Jin Jing was described as a "secret martial arts manual".

Zhou believes that some of the descriptions of Yi Jin Jing in current Chinese martial arts novels may have adopted this setting from historical materials of the Qing Dynasty while adding more rich and complex plot lines.

Yijin Jing also introduces finger strength training, which involves placing mung beans in a container and repeatedly inserting fingers among the beans to strengthen the hand. Over time, the fingers become as hard as stone and no one can resist them.

Some people believe that this may be one of the legendary Dian Xue techniques. However, Zhou believes that the ability to immobilize people with this technique may not actually exist. The miraculous effects are mostly exaggerated in novels and movies.
