Yang Lu-ch'an or Yang Luchan, simplified Chinese: 杨露禅; traditional Chinese: 楊露禪; pinyin: Yáng Lùchán; also known as Yang Fu-k'ui (simplified Chinese: 杨福魁; traditional Chinese: 楊福魁; pinyin: Yáng Fúkuí) (1799-1872), born in Kuang-p'ing (Guangping), was an influential teacher of the soft style martial art t'ai chi ch'uan (Taijiquan) in China during the second half of the 19th century. He is known as the founder of Yang-style t'ai chi ch'uan.

Yang Lu-ch'an’s family was a poor farming/worker class from Hebei Province, Guangping Prefecture, Yongnian County. Yang would follow his father in planting the fields and, as a teenager, held temporary jobs. One period of temporary work was spent doing odd jobs at the Tai He Tang Chinese pharmacy located in the west part of Yongnian City, opened by Chen De Hu of the Chen Village in Henan Province, Huaiqing Prefecture, Wenxian County. As a child, Yang liked martial arts and studied Changquan, gaining a certain level of skill.

One day Yang reportedly witnessed one of the partners of the pharmacy utilizing a style of martial art that he had never before seen to easily subdue a group of would-be thieves. Because of this, Yang requested to study with the pharmacy's owner, Chen De Hu. Chen referred Yang to the Chen Village to seek out his own teacher—the 14th generation of the Chen Family, Ch'en Chang-hsing.

Yang Cheng (simplified Chinese: 杨程; traditional Chinese: 楊程; pinyin: Yáng Chéng; born 11 October 1985 in Tianjin) is a Chinese football goalkeeper who currently plays for Shandong Luneng in the Chinese Super League.

Originally starting his career with the Tianjin Locomotive youth team Yang Cheng would move to the Shandong Luneng youth team in 2000 where he would graduate through the various youth squads. He would eventually graduate to the senior team and for several seasons was used as an understudy and would later make his league debut on April 2, 2005 against Inter Shanghai in a 2-1 win. Despite being a promising young player head coach Ljubiša Tumbaković surprised many when he persisted in making Yang Cheng his first choice goalkeeper throughout the season and while Shandong finished the season in third Li Leilei was brought into the squad at the beginning of the 2006 league season to add more experience towards the team.

Under head coach Eckhard Krautzun Yang Cheng would be the first choice goalkeeper for the U-20 Chinese football team in the 2005 FIFA World Youth Championship held in the Netherlands. While he would aid China to the knock out stages of the competition Yang Cheng would find himself at fault for China's defeat to Germany when he conceded a penalty that saw Germany win 3-2.
