The beginning of the twentieth century was the golden age of Praying Mantis Kung Fu and the Three Mountains of Laiyang were paramount to its fame. During the Qing Dynasty the style was practiced by few people, in relative secrecy. However with the founding of the Republic of China things changed, and martial arts were being promoted as a national sport that all should practice. During this time Song Zi De, along with his teacher and sworn brother, Jiang Hua Long, began to openly teach the art. Song had 8 top disciples, however three of them gained a reputation unrivaled, being known far and wide for their martial prowess. They were Cui Shou Shan, Wang Yu Shan and Li Kun Shan. Together they were known as the “Three Mountains of Laiyang”, or Laiyang San Shan, as their names all shared the character Shan 山.
