As the curtain of night is hanging down, nightlife starts after a busy day. Nowadays, Chinese people are finding their nightlife more colorful and themselves intoxicated（使陶醉）in various entertaining ways. Many young well-paid white collars regard the night as their hard-earned reward for a long, highpressure working day.
However, in ancient times, going out after dark was actively discouraged in order to instill（灌输）temperate（有节制的） habits in the popuLace（民众）. Centuries ago, night-time activities had either politically subversive（暗中破坏的) or corrupt connotations. It is the ongoing evolution from an agricultural to an industrial society that altered the traditional Chinese concept of night. The development of science and technology has also gradually changed the traditional attitudes towards nightlife. The first introduction of gas light made it possible for people to step out of their homes in the evening, and go to public places of entertainment- teahouses, bars, and theaters. Evening gradually became a time for recreation.
