This is a type of energy healing known as Zhineng Qigong.
It was practiced at the First Medicine-less Hospital in the World, near Beijing.
They used Zhineng QiGong to heal people without medicine or surgery.
The Huaxia Zhineng Qigong Clinic operated with a 95% success rate from 1988 to 2001.
It was shut down by the government for political reasons (read: they were healing too many people.)
Then the QiGong itself was banned and hundreds of thousands of practitioners were arrested and detained.
There are places today where it is still “illegal”.
