Asia
In the Chinese capital of Chang'an, the West Market (and East Market) are closed every night one hour and three quarters before dusk (by government order); the curfew is signaled by the sound of 300 beats to a loud gong. After the official markets have been closed for the night, small night markets in residential areas thrive with plenty of customers, despite government efforts to shut them down. With the decline of the government's authority (by mid 9th century), this edict (like many others) is largely ignored, as urban dwellers keep attending the night markets regardless.
