Chinese martial arts have long talk "qigong", but systematic exposition to the number of martial arts qigong Chang Ying Yang sishui people are weeks' training in gas theory "is expensive.
Since the founding of Taijiquan Chen Ting, rumored to XIV Yang Lu Chan Fang Chen Changxing, then, in order to meet the different needs of different learning objects and derived from a variety of tribes gradually Fort Zhao frame, Yang, Wu, Wu and Sun style and so on.
In 1989, in order to meet the development needs of the martial arts, Chinese Wushu Research Institute prepared the Chen, Yang, Wu and Sun style Taijiquan competition routine.
Taijiquan follow the "gatekeeper and", "feast", "Tan Siu Lin," "defending the weak," the traditional thinking requires both boxing training the mind first, but also requires calm cortisol, humbly solid web, gas Shen Dan Tian, loose soft uniform slow.
Youyi Book of Changes, breathing, guided, yin and yang philosophy, meridian meteorological dedicated to martial arts, boxing management of research, Shanfanjiujian, and finally set the essence of martial arts factions, creating a self-proclaimed martial art of Chang and theories, Li Chang boxing in the Central Plains.

The Tauc plot is shown in Figure 5, and it can be seen that the bandgap energy of CaTiO3 was found to be approximately 3.48 eV (315 nm) and is similar to the previous reported by Yang et al.
