A Jiangsu Han Chinese named Shen Qiliang wrote books on Manchu grammar like 清書指南 (Guide to Qing Books, "Manju bithe jy nan") and 大清全書 (Great Qing Encyclopedia, "Daicing gurun-i yooni bithe"). He was born to a father who was a naval officer for the Qing, and his grandfather was an official of the Ming dynasty, before rebels murdered him. Shen Qiliang himself fought against the Three Feudatories as part of the Qing army. He then started learning Manchu and writing books on Manchu grammar from Bordered Yellow Manchu Bannermen in 1677 after relocating to Beijing. He translated the Hundred Family Names and Thousand Character Classic into Manchu and spent 25 years on the Manchu language. Shen wrote: "I am a Han. But all my life I have made a hobby of Manchu." Shen never had to learn Manchu as part of his job because he was never an official so he seems to have studied it of his own will. Most Han people were not interested in learning non-Han languages so it is not known why Shen was doing it.
