Xing Yi Quan
Yang Jwing-Ming (who is not a practitioner of the art) argues that aspects of Xing Yi Quan (particularly the animal styles) are identifiable as far back as the Liang Dynasty at the Shaolin Temple. According to Jwing-Ming, Yue Fei therefore did not strictly invent Xing Yi Quan, but synthesized and perfected existing Shaolin principles into his own style of gongfu which he popularized during his military service. Nonetheless, according to Yang, Yue Fei is usually identified as the creator because of his considerable understanding of the art (as shown in the work "The Ten Theses of Xingyiquan", credited to Yue) and his cultural status as a Chinese war hero. It ought be noted that in Chinese culture, it is common to attribute the creation of great traditions to legendary individuals. In such a way, the art of Tai Ji Quan is attributed to the legendary Zhang Sanfeng, and Daoism to Laozi, even though as in the case with Yue Fei, there exists no proof for such claims.
