The New York times has a great op-ed on Shanghai’s efforts to crack down on residents wearing pajamas everywhere as they prepare for the 2010 World Expo:
Catchy red signs reading “Pajamas don’t go out of the door; be a civilized resident for the Expo” are posted throughout the city. Volunteer “pajama policemen” patrol the neighborhoods, telling pajama wearers to go home and change. Celebrities and socialites appear on TV to promote the idea that sleepwear in public is “backward” and “uncivilized.”
But many residents disagree. Pajamas — not the sexy sleepwear you find at Victoria’s Secret, but loose-fitting, non-revealing PJs made of cotton or polyester — have been popular in Shanghai since the late 1970s, when Deng Xiaoping, then China’s leader, sought to modernize the economy and society by “opening up” to the outside world. The Chinese adopted Western pajamas without fully understanding their context. Most of us had never had any dedicated sleepwear other than old T-shirts and pants. And we thought pajamas were a symbol of wealth and coolness.
Shanghainese began wearing them to bed — but kept them on to walk around the neighborhood, mainly out of convenience. At that time in Shanghai, people lived in crammed, communal-style quarters in shikumen — low-rise townhouses in which families shared toilets and kitchens. Through the 1980s and ’90s, the average person had less than 10 square meters of living area. To change out of one’s pajamas just to walk across the road to the market would be too troublesome and unnecessary.
