History of Kung Fu...
Kung Fu emerged in the 5th Century AD, in the Hunan province of China at the Northern Shaolin Temple on Songshan mountain witch was also the birthplace of Zen Buddhism. The beginning of kung Fu is attributed to a Buddhist monk called Da Mo or Boddhidarma, Da Mo originated from India and went to China 527 AD or there about.

Da Mo found that the Buddhist monk’s health suffered because 

of frailty and old age, they where unable to meditate for long periods of time which their religious beliefs demanded. Da Mo began to setup a system of physical exercise to help the body, and a method of breathing that helped to increase the amount and power of a persons Chi, and in turn strengthen the bodies inner organs, to bring health and long life.
 
It was these physical and breathing exercises as well as two texts that Da Mo wrote Yi Jin Jing and Xi Sui Jing that formed the basis of Kung Fu, the exercises were devised by watching and following the movements of animals. By imitating animals as they fought many fighting styles evolved like Tiger and Crane. Da Mo ideas and teachings spread throughout China, then to Japan (Karate) and Korea (Taekwando). The monks living in the Northern Temple created many new and differing styles of Kung Fu most of which are still performed today.
 

History of Kung Fu in Southern China...

 
In 1399 AD the second of the Kung Fu Shaolin Temples was built in Southern China in Fukien province (now Fujian province), the styles where based on the Northern Shaolin Temples Kung Fu, and developed along the same road until 1644 AD when the Ming Dynasty fell to the Ching (Manchu) Dynasty. In the South of China there was great resistance to the Ching Dynasty, the Fukien Temple was the centre of the rebellion cause of many uprisings.

The Southern Temples monk’s along with many Martial artists like Gee 

Sim Sin Si who was the last Abbot of the Fukien Temple and his pupils Fong Sai Yuk, Luk Ah Choy and Hung Hei Guen and many others defended the Temple against attack from the Ching’s for over 150 years. With the help of the traitor Ma Ling Yee who was also a pupil of Gee Sim Sin Si, in 1800 AD the Ching’s sent the full force of the Imperial Army. Many monks where killed and the Temple was razed to the ground. But many monks escaped and went underground.
 
The Ching's hunted the escaped monks and killed as many as they could find, but some of the fugitives carried on the teaching, Luk Ah Choy and Hung Man Ting disguise their kung fu and renamed it Hung Kuen. Kung Fu in South China from that time on consisted of family styles that where handed down from generation to generation. So there may not be a Shaolin Temple in Southern China, but the development of Kung Fu in the south continues to this day. And the Northern Shaolin Temple in Hunan province is considered a national centre for learning and the development of Kung Fu.
