Dr. Rev. Nathan Sites was graduated from Ohio Wesleyan University . In 1861, he reached Foochow with his wife Sarah Moore Sites to begin his oversea missionary work which would last until his death. Upon his arrival, Sites chose to live in a countryside hamlet among native villagers to experience the rural life of the Chinese. During his missionary life in China, Sites met with many obstacles: one day while carrying out the reconstruction work of the local church in Nanping, he was brutally beaten by an enraged mob, who left a deep scar on his face. Like other missionaries, Sites argued and labored for the creation of a strong and independent Chinese Church, and in this effort he ordained many of the earliest native Christian ministers like Sia Sek Ong.
