Yang Lu Chan or Yang Luchan, also known as Yang Fu-k’ui or Yang Fukui (1799–1872), born in Guangping, was an influential teacher of the art of Tai Chi Chuan (Taijiquan) in China during the second half of the 19th century. He is known as the founder of Yang-style tai chi chuan, the most popular and widely practised style in the world today.
Yang became famous for never losing a match and never seriously injuring his opponents. Having refined his martial skill to an extremely high level, Yang Lu Chan came to be known as Yang Wudi (Yang the Invincible)
Yang Chengfu was born into the famous Yang Taijiquan family, the son of Yang Chien-hou and grandson of Yang Luchan. With his older brother Yang Shao-hou and colleagues Wu Jianquan and Sun Lutang, he was among the first teachers to offer Tai Chi Chuan instruction to the general public at the Beijing Physical Culture Research Institute from 1914 until 1928. He moved to Shanghai in 1928.
Yang Chengfu or Yang Cheng-fu is historically considered the best known teacher of the soft style martial art of Yang-style Tai Chi Chuan.
