Encyclopædia Britannica, Ninth Edition/Chapu
CHAPU, an important maritime town of China, in the province of Che-keang, 50 miles N.W. of Chinhai, situated in one of the richest and best cultivated districts in the country. It is the port of Hang-chow, with which it has good canal communication, and it was formerly the only Chinese port trading with Japan. The town has a circuit of about five miles, exclusive of the suburbs that lie along the beach; and the Tatar quarter is separated from the rest by a wall. It was attacked and much injured by the British force in 1842, but was abandoned immediately after the engagement.
