Morrison cooperated with such contemporary missionaries as Walter Henry Medhurst and William Milne (the printers), Samuel Dyer (Hudson Taylor's father-in-law), Karl Gützlaff (the Prussian linguist), and Peter Parker (China's first medical missionary). He served for 27 years in China with one furlough home to England. The only missionary efforts in China were restricted to Guangzhou (Canton) and Macau at this time. They concentrated on literature distribution among members of the merchant class, gained a few converts, and laid the foundations for more educational and medical work that would significantly impact the culture and history of the most populous nation on earth. However, when Morrison was asked shortly after his arrival in China if he expected to have any spiritual impact on the Chinese, he answered, "No sir, but I expect God will!"
