The pace of missionary activity increased considerably after the First Opium War in 1842. Christian missionaries and their schools, under the protection of the Western powers, went on to play a major role in the Westernization of China in the 19th and 20th centuries. Liang Fa ("Leung Faat" in Cantonese) worked in a printing company in Guangzhou in 1810 and came to know Robert Morrison, who translated the Bible to Chinese and needed printing of the translation. When William Milne arrived at Guangzhou in 1813 and worked with Morrison on translation of the Bible, he also came to know Liang, whom he baptized in 1816. In 1827, Liang was ordained by Morrison, thus becoming a missionary of the London Missionary Society and the first Chinese Protestant minister and evangelist.
