In Macau, and later in Hong Kong, Gützlaff worked on a Chinese translation of the Bible, published a Chinese-language magazine, "Eastern Western Monthly Magazine", and wrote Chinese-language books on practical subjects. In 1834 he published "Journal of Three Voyages along the Coast of China in 1831, 1832 and 1833". Along the way he handed out tracts which had been prepared by another pioneer missionary to China, Robert Morrison. In late 1833, he acted as naturalist George Bennett's Cantonese interpreter on his visit to Canton.
