Shang-hae

Connected, however, as it is by an elaborate system of inland navigation with all the principal cities of the rich and productive province in which it is situated, among which Soo-chow-foo, the most important manufacturing town of the empire, occupies the foremost rank, Shang-hae must necessarily serve as the entrepôt of a considerable export and import trade, receiving, in exchange for the stuffs, silks, and wares of the province, the cargoes of grain, metals, and woollen goods, brought by the junks from Japan, Corea, Formosa, the southern ports, and Singapore.[…] Shang-hae is apparently a very ancient town, bearing on its walls and buildings, private as well as public, evidence of the ravages of long periods of time.

The city of Shang-hae is surrounded by a wall about three miles and a quarter in circuit, which is not fortified in any manner; there are six entrances at gates, which give ingress and egress to the inhabitants of the city and environs; four of these gates open into the neighbourhood of the river where the warehouses of the merchants are situated.
