In 1924, he worked for YMCA, managing its schools and then went to the United States to study at Union Theological Seminary (affiliated with the Columbia University) at New York City, from which he earned a master's degree in philosophy.
[4] Wu, along with four other Protestant and two Buddhist leaders attended the first Chinese People’s Political Consultative Conference (CPPCC) in Beijing from September 21 through 30, 1949.
Following an April 1951 conference, the Preparatory Committee of the Chinese Christian Resist-America-Aid-Korea Three-Self Reform Movement (TSRM) was formed with Wu as it chairman.
[2] In an address to the conference that marked that transition, he denounced Hudson Taylor, the late founder of the China Inland Mission, as an imperialist tool.
Wu died in Beijing on 17 September 1979, one year before the re-establishment of the Three-Self Patriotic Movement and the creation of the China Christian Council, both of which were led for nearly two decades by Bishop K.H.
[9] From the mid-1930s until 1949, Wu started to appreciate and sympathize with the communist theory of social revolution and he gradually came to the opinion that communism would be the only instrument for national salvation.
[11] In response to the communist campaign to purge the political sphere of the impact of the so-called "Three Mountains" of imperialism, feudalism, and bureaucratic capitalism, the churches which participated in the TSPM started to express hostility towards foreign missions.
