Guo Yunshen (simplified Chinese: 郭云深; traditional Chinese: 郭雲深; pinyin: Guō Yúnshēn) (1829 - 1898) was a famous Xingyiquan master. He represented the xingyi martial philosophy of preferring to become highly proficient with only a few techniques rather than to be less proficient with many techniques. His skill with one technique Beng Quan was legendary: it was said from him that "with his 'half-step bengquan', he could fight anyone under heaven without finding an equal." (banbu bengquan da yu tianxia wu dishou), and earned the nickname "the steadfast" (bu daota).
