There were no nightclubs or bars in 1980's Beijing such as the ones portrayed in Summer Palace. Despite the presence of a few underground bars in Beijing at that time, it is highly improbably that any university students would patron such establishments. Moreover, those bars did not play American pop music, did not allow dancing, did not stock western liquor, and certainly did not admit foreigners. Any clubs or bars like the ones shown in Summer Palace did not begin appearing in Beijing until the late 1990s and did not gain popularity amongst middle-class college students until after the new millennium.
The fashionable clothing worn by characters Yu Hong and Zhou Wei throughout their scenes as university students simply did not exist in China at this time nor for at least another decade. Mainland Chinese students circa the 1980s would have worn nondescript, non-branded attire rather than the high-heels, hipster track suits, designer dresses and sexy lingerie worn by the actors and actresses in Summer Palace.
