The grandmaster was a weakling since birth, and suffered from congenital liver ailment, lung disease, among others. He barely survived after treatment from physicians. At age of nine, his parents sent him to martial art training, first under Master Wu Chian Chuan, for a period of eight years. After that, he learned under the tutelage of Grandmaster Yang Sao Hou for some four years.
At the time when China became a republic, Grandmaster Wu was an accomplished archaeologist, and was also a member of the First Legislative Assembly of the Republic of China.
Grandmaster Wu devoted his whole life to the research and learning of Tai Ji, and traveled widely in meeting and sharing views on Tai Ji with other masters. Grandmaster emphasized that both theory and practical of Tai Ji were equally important, and pioneered the teaching of Tai Ji in a scientific and systematic way, and the application of the art in health maintenance and preservation.
Grandmaster Wu passed away in 1989, without any illness, at the ripe old age of 108. (His wife, Grandmistress Liew is now aged 107, and is billed at the Number One Healthy Grand Old Lady of Beijing.)
Grandmaster Wu's martial art skill had reached a very high standard. He could exert his inner strength on a person from the distance of one metre, causing that person to fall a few yards away. He is indeed a great master of Tai Ji, and during his lifetime had imparted the real knowledge and skill to only two persons, namely GrandUncle Ma Yu Ching, and Grandmaster Sim Po Ho.
