The Term NO 2 Health Boosting Chi ( Qi ) Gong Daoyin exercise comes from the LU SHI ( Grand History ) by LUO MI (1131-1189 ) during the Song Dynasty :”In the time of Yinkang ( an ancient ruler ), the ditches were not dredged and the water did not flow. It was wet and gloomy, the air was stuffy, and most people suffered poor circulation, stiff muscles and swollen feet. So, Yinkang ordered people to do dance ( No 2  Daoyin exercise ) to ease their joints, and taught people to lead the exercise and convince people of its benefit.​

​

There also descriptions of people practicing or “swelling-relieving dance “ to “ improve circulation “ and “ ease joints “ in the Shang Shu ( Book of History ) complied in the Han Dynasty. The Huang Di Nei Jing ( Yellow Emperor’s Canon of Medicine ) also says: The land in the centre is flat and wet, and all things grew there. Its people ate everything and did not much labor. So most people were affected by numbness of limbs, cold and heat, and their best treatment was Daoyin and massage.” From these description, we know that “ dance “ was directly related to “ Dao “; and “ dance “ fall into the category of “ Daoyin “ ( traditional body-building exercise which combines breath control, body and limb movements, concentration of mind, and local massage ) and have the same effect.

​

Apart from historical records documenting NO 2 exercise features many movement of the dances of the people in the picture of DAOYIN exercise ( under from the Han Dynasty tomb at Mawandui in Changsha, Hunan Province ) also provided important historical information for choreographing the Health Qigong ( Chi Gong ). Among some Stone Age tomb artifacts unearthed in Qinhan Province was a basin of the Majiayao culture of 5000 years ago, painted with vivid forms true-to-life dancing figures of ancient Qi Gong ( Chi Gong ). Chinese cliff paintings, murals and silk paintings from ancient times also recorded an abundance of “ dancing “ elements. The Zenghouyi Chimes unearthed in Suizhou of Hubei province and the dance with its music accompaniment indicate many forms of dancing with musical accompaniment, providing an important basis for the study of the forms and characteristics of the movements of these primitive “ dances”. Therefore, both the written records of the dance and the picture of real objects of dance showed that the Chinese ancestors knew how to use the form of “ dance “ to relieve pains of illness and restore health.

​

Choreographing the dance as exercise today enriches the practice of Qi Gong ( Chi Gong ) to preserve health, with emphasis on “ easing joints “ and using “ dancing to relieve pains through circulation”. Uses limb movement, breath and concentration of the mind to regulate the inner organs, promote circulation of QI and blood, replenish vital energy and recover from illness, thus promoting fitness.
