Background: Ai Weiwei (Chinese: Ai Wei Wei ; pinyin: Ai Weiwei, English pronunciation ; born 28 August 1957 in Beijing) is a Chinese contemporary artist and activist. His father's (Ai Qing) original surname was written Jiang (Jiang ). Ai collaborated with Swiss architects Herzog & de Meuron as the artistic consultant on the Beijing National Stadium for the 2008 Olympics.
Context: On 22 June 2011, the Chinese authorities released Ai from jail after almost three months' detention on charges of tax evasion. Beijing Fa Ke Cultural Development Ltd. (Chinese: Bei Jing Fa Ke Wen Hua Gong Si ), a company Ai controlled, had allegedly evaded taxes and intentionally destroyed accounting documents. State media also reports that Ai was granted bail on account of Ai's "good attitude in confessing his crimes", willingness to pay back taxes, and his chronic illnesses. According to the Chinese Foreign Ministry, he is prohibited from leaving Beijing without permission for one year. Ai's supporters widely viewed his detention as retaliation for his vocal criticism of the government. On 23 June 2011, professor Wang Yujin of China University of Political Science and Law stated that the release of Ai on bail shows that the Chinese government could not find any solid evidence of Ai's alleged "economic crime". On 24 June 2011, Ai told a Radio Free Asia reporter that he was thankful for the support of the Hong Kong public, and praised Hong Kong's conscious society. Ai also mentioned that his detention by the Chinese regime was hellish (Chinese: Jiu Si Yi Sheng ), and stressed that he is forbidden to say too much to reporters. After his release, his sister gave some details about his detention condition to the press, explaining that he was subjected to a kind of psychological torture: he was detained in a tiny room with constant light, and two guards were set very close to him at all times, and watched him constantly. In November, Chinese authorities were again investigating Ai and his associates, this time under the charge of spreading pornography. Lu was subsequently questioned by police, and released after several hours though the exact charges remain unclear. In January 2012, in its International Review issue Art in America magazine featured an interview with Ai Weiwei at his home in China. J.J. Camille (the pen name of a Chinese-born writer living in New York), "neither a journalist nor an activist but simply an art lover who wanted to talk to him" had travelled to Beijing the previous September to conduct the interview and to write about his visit to "China's most famous dissident artist" for the magazine. On 21 June 2012, Ai's bail was lifted. Although he is allowed to leave Beijing, the police informed him that he is still prohibited from traveling to other countries because he is "suspected of other crimes," including pornography, bigamy and illicit exchange of foreign currency. Until 2015, he remained under heavy surveillance and restrictions of movement, but continues to criticize through his work. In July 2015, he was given a passport and may travel abroad.
Question: what did he speak about?
Answer:

Background: Mwai Kibaki, C.G.H. (born 15 November 1931) is a Kenyan politician who was the third President of Kenya, serving from December 2002 until April 2013. Kibaki was previously Vice-President of Kenya for ten years from 1978 to 1988 under President Daniel arap Moi. He also held cabinet ministerial positions in the Kenyatta and Moi governments, including time as minister for Finance (1969-1981) under Kenyatta, and Minister for Home Affairs (1982-1988) and Minister for Health (1988-1991) under Moi. Kibaki served as an opposition Member of Parliament from 1992 to 2002.
Context: Kibaki was born in 1931 in Kikuyu village, Othaya division of Kenya's then Nyeri District, now Nyeri County. He is the youngest son of Kikuyu peasants Kibaki Githinji and Teresia Wanjiku. Though baptised as Emilio Stanley by Italian missionaries in his youth, he has been known as Mwai Kibaki throughout his public life. Family oral history maintains that his early education was made possible by his much older brother-in-law, Paul Muruthi, who insisted that young Mwai should go to school instead of spending his days grazing his father's sheep and cattle and baby-sitting his little nephews and nieces for his older sister. Kibaki turned out to be an exemplary student. He attended Gatuyaini School for the first two years, where he completed what was then called Sub "A" and sub "B" (the equivalent of standard one and two or first and second grade). He later joined Karima mission school for the three more classes of primary school. He later moved to Mathari School (now Nyeri High School) between 1944 and 1946 for Standard four to six, where, in addition to his academic studies, he learnt carpentry and masonry as students would repair furniture and provide material for maintaining the school's buildings. He also grew his own food as all students in the school were expected to do, and earned extra money during the school holidays by working as a conductor on buses operated by the defunct Othaya African Bus Union. After Karima Primary and Nyeri Boarding primary schools, he proceeded to Mang'u High School where he studied between 1947 and 1950. He passed with a maximum of six points in his "O" level examination by passing six subjects with Grade 1 Distinction. Influenced by the veterans of the First and Second World Wars in his native village, Kibaki considered becoming a soldier in his final year in Mang'u. However, a ruling by the Chief colonial secretary, Walter Coutts, which barred the recruitment of the Kikuyu, Embu and Meru communities into the army, put paid to his military aspirations. Kibaki instead attended Makerere University in Kampala, Uganda, where he studied Economics, History and Political Science, and graduated best in his class in 1955 with a First Class Honours Degree (BA) in Economics. After his graduation, Kibaki took up an appointment as Assistant Sales Manager Shell Company of East Africa, Uganda Division. During the same year, he earned a scholarship entitling him to postgraduate studies in any British University. He consequently enrolled at the prestigious London School of Economics for a B.Sc. in public finance, graduating with a distinction. He went back to Makerere in 1958 where he taught as an Assistant Lecturer in the economics department until 1961. In 1961, Kibaki married Lucy Muthoni, the daughter of a church minister, who was then a secondary school head teacher.
