Wu Yihui 吳翼翬 (Cantonese Ng Yik-fai) (1887 – 1958) was a Chinese martial artist and scholar.
He was the first person to open teachings and spread the art of Liuhebafa in public, and was a prominent fighter and instructor who influenced many of the masters of his generation.
He was from a scholarly and official family, and a man of good nature who had strong martial art talents.
He graduated from Baoding Military Academy in 1907 and was dispatched to the Beiyang Army, where he was appointed to staff officer of the first division.
The next year, when the Japanese war began, he moved with the Central Martial Arts Academy first to Vietnam's Burma, later settling in Yunnan's Kunming.
Wang Xiangzhai, the creator of Yiquan, made a public statement regarding Wu Yihui in 1928 saying, "I have traveled across the country in research, engaging over a thousand people in martial combat, there have been only 2.5 people I could not defeat, namely Hunan's Xie Tiefu, Fujian's Fang Yizhuang and Shanghai's Wu Yihui."
