Air pollution in Beijing was at hazardous level in the past few days. Even a little haze can harm human body over the long term. The World Health Organization warns that high levels of pollution are linked with respiratory infections, lung cancer and heart disease. Officials and experts have advised residents, especially children and the elderly, to stay indoors. Many of those who ventured out wore face masks with various patterns to protect themselves against the thick layer of smog covering the city. The pure cotton, gauze masks of cartoon or fashion style form a unique scene in the city.
