If you have some info regarding some Kungfu Legends or Heroes in China, you can add them here.

Here is some profiles that I found while surfing on the net :

1. Zhang San Feng

One tradition claims that Master Chang San-Feng was born at midnight on April 9, 1247 AD,
near Dragon-Tiger Mountain in Kiang-Hsi Province in the southeast of China. He is
said to have been a government official in his youth, learned Shaolin martial arts while
living in the Pao-Gi Mountains near Three Peaks (San Feng), and then living for scores
of years as a Taoist hermit and sage in the Wu-Tang (Wudang) Mountains. He is reported to
have lived to be 200 years old (1247-1447AD), but his death date is uncertain. He would
have lived in the Sung, Yuan, and Ming Dynasties if these dates were accurate. (Jou, 1980)

Master Chang is known by a variety of names: Chang San-Feng, Cheng San Feng,
Chang Chun Pao, Chang Sam Bong, Zhang Sanfeng, Chang Tung, Chang Chun-pao,
Grandmaster Chang, Chang the Immortal, Immortal Chang, Zhangsanfeng.

The early legends about Chang San-Feng are linked with activities of Emperor Chengzu
(1403-1424) who searched for Chang and other political refugees. By 1459, Chang
had been declared an Immortal and, as with most saints, stories of his miraculous
powers became part of the folklore in the Wudang Mountain area. There is a fairly
long tradition amongst Wundang Mountain martial artists and Taoists that attributes
the development of soft style martial arts to Chang San-Feng and his disciples
(Yeo, 2001). In 1670, Huang Zongxi wrote a book called Epitaph for Wang
Zhengnan in which Chang San-Feng was called the founder of internal martial
arts practiced near Mount Wudang. By the 1870's, Yang family Taiji teachers
were claiming that Chang San-Feng was the originator of Tai Chi Chuan.
