The former head of Google China and influential Micro-blogger Kai-Fu Lee posted[zh] to his 32 million fans on Sina Weibo an imaginary conversation between a Beijinger and a Shanghainese:

Beijinger: “We Beijingers are the most fortunate, we can open the window and have free cigarettes.” Shanghainese: “That's nothing, we can enjoy pork soup simply by turning on our faucets!!”

This sarcastic dialogue refers to the terrible air pollution in Beijing and the dead pigs found floating in Shanghai’s main water source, the Huangpu river. The dialogue was retweeted over 61, 790 times since it was posted on March 13, 2013.
