The birth control therapy sprouted in the Qin and Han Dynasties. It was based on the Wei and Jin Dynasties, flourished in the Sui and Tang Dynasties, and was perfected in the Song and Yuan Dynasties. It had a long history of development and formed many different methods of practice. However, the basic method of practice is inseparable from abdominal breathing and breath-holding exercises. After the Tang and Song dynasties, they also introduced the method of static induction and intentional adjustment of interest rates on the basis of this, making it more rigorous and reasonable. In a sense, the essence of qigong health (especially static power) is also among them.
Regarding the meaning of "child birth", the Qigong community also has different opinions. Some people think that the birth is the complete suspension of natural breathing (external breathing) and reliance on internal breathing to maintain its life activities, which is a qualitative difference from the notion that "closing up" (short-term natural breathing) or extreme slowing down of natural breathing frequency is generally considered. In ancient literature, there was also a record of continual cessation of the birth to the complete discontinuation of natural respiration and long-lasting records. Indian yoga has similar records. However, for beginners or those who are used to prevent diseases, they should not be persistent and force to enter such a realm in order to avoid going astray.
