Liang Fa (Leung Fat) worked in a printing company in Guangzhou in 1810 and came to know Robert Morrison (missionary) (1782-1834, a missionary sent by the London Missionary Society in Britain and the first Christian Protestant missionary in China), who translated the Bible to Chinese and needed printing of the translation. When William Milne (missionary) (1785-1822, another missionary sent by the London Missionary Society) arrived at Guangzhou in 1813 and worked with Morrison on translation of the Bible, he also came to know Liang Fa. Liang was baptized by Milne in 1816. In 1821, Liang was ordained by Morrison, thus becoming a missionary of the London Missionary Society and the first Chinese Protestant minister and evangelist.
Western Medicine was introduced to China in the 19th Century, mainly by medical missionaries sent from various Christian mission organizations, such as the London Missionary Society (Britain), the Methodist Church (Britain ) and the Presbyterian Church in the United States. Benjamin Hobson (1816-1873), a medical missionary sent by the London Missionary Society in 1839, set up a highly successful Wai Ai Clinic and others worked there. Liang Fa baptized Chau in 1852. The Methodist Church based in England sent missionary George Piercy to China. In 1851, Piercy went to Guangzhou, where he worked in a trading company. In 1853, he started a church in Guangzhou. In 1877, Chau was ordained by the Methodist Church in Guangzhou, where he pastored for 39 years.

Fulton (1854-1927) was sent by the Foreign Missions Board of the Presbyterian Church in the United States to found the first medical college for women in China. Known as
