Apart from its work as a school, the college also trained evangelists and pastors. Amongst them, former student Rev. Hoh Fuk Tong () was made pastor in 1846. He preached in Foshan and Canton to his fellow Chinese people. Liang Fa (also known as Leung Faat), who was a craftsman in the printing centre of the college, also heeded the call to preach Gospel. A printing press was set up within the school premises to publish translated Bible and other religious publications.
