The idea of Bodhidharma influencing Shaolin boxing is based on a qigong manual written during the 17th century. This is when a Taoist with the pen name 'Purple Coagulation Man of the Way' wrote the "Sinews Changing Classic" in 1624, but claimed to have discovered it. The first of two prefaces of the manual traces this succession from Bodhidharma to the Chinese general Li Jing via "a chain of Buddhist saints and martial heroes." The work itself is full of anachronistic mistakes and even includes a popular character from Chinese fiction, the 'Qiuran Ke' ('Bushy Bearded Hero') (), as a lineage master. Literati as far back as the Qing Dynasty have taken note of these mistakes. The scholar Ling Tinkang (1757–1809) described the author as an "ignorant village master."
