"The national college, or Han-lin-yuen, is a body of learned doctors, who have arrived at the most extensive celebrity, and are the guardians of Chinese literature. They are eligible to the highest offices of state, and exercise great influence in the most important affairs of government. Their learning consists in the knowledge of the Chinese classics, works which a schoolboy cons, and a Hanlin explains. General knowledge is excluded from this department. If they can write a good essay, discourse upon the doctrines of Confucius, and unite with this a knowledge of their own country, and a few imperfect geographical notions, they are truly learned men. But wo unto him who should be daring enough to utter anything beyond what Confucius has taught. Their learning does not consist in examining, but in blindly following established principles.”
