In 1931, the Roman Catholic Church appointed Bonifacius Yeung as the auxiliary bishop of the Vicariate Apostolic of Guangzhou. Due to the fact that relevant historical documents have remained overseas, little attention to Yeung and his appointment has been given by Chinese scholars. This appointment was first proposed by Antoine Fourquet in 1926, promoted by the Non-Christian Movement and other social movements in Guangzhou, as well as the indigenization of Catholicism led by the Roman Catholic Church in the first half of the 20th century. The twists and turns of the installation of the Chinese auxiliary bishop reflect the divided views on relation between the Church and local society among the missionaries in China during the era of Republic of China. It also indicates the different considerations of the route in developing the local Church. The event is exemplary in the history of Catholicism in the Republic of China. Antoine Fourquet, as a key figure in this event, his forward thinking still has value and relevance today.
