During the early years, when trained social work personal was almost completely unavailable, MOCOR worked along with other agencies to meet the needs of Hong Kong on an emergency basis. When the Wei Li Kung Hui was in a position to develop its own local casework and relief programmes, MOCOR was ready to establish the Yang Social Service Centre (YSSC), which was managed by the Ward Memorial Methodist church in 1967, in memory of Rev Chester Yang, the founding pastor of the Ward Memorial Methodist Church. The new building of YSSC and Ward Memorial Methodist Church situated at the Waterloo Road were dedicated to open on October 29, 1967.
The Wei Li Kung Hui and the Chinese Methodist Church united in 1975 and formed the new Methodist Church, Hong Kong. In September 1990, YSSC was renamed as the Yang Memorial Methodist Social Service.
