Ai Weiwei (Chinese: 艾未未; pinyin: "Ài Wèiwèi", English pronunciation (·info); born 28 August 1957) is a Chinese contemporary artist and activist. Ai grew up in the far north-west of China, where he lived under harsh conditions due to his father's exile. As an activist, he has been openly critical of the Chinese Government's stance on democracy and human rights. He investigated government corruption and cover-ups, in particular the Sichuan schools corruption scandal following the collapse of "tofu-dreg schools" in the 2008 Sichuan earthquake. In 2011, Ai Weiwei was arrested at Beijing Capital International Airport on 3 April, for "economic crimes". He was detained for 81 days without charge. Ai Weiwei emerged as a vital instigator in Chinese cultural development, an architect of Chinese modernism, and one of the nation's most vocal political commentators.
