Problem: Daniel Barenboim (born 15 November 1942) is an Argentine-Israeli pianist and conductor who is a citizen of Argentina, Israel, Palestine, and Spain. He is the general music director of the Berlin State Opera, and the Staatskapelle Berlin; he previously served as Music Director of the Chicago Symphony Orchestra, the Orchestre de Paris and La Scala in Milan. Barenboim is known for his work with the West-Eastern Divan Orchestra, a Seville-based orchestra of young Arab and Israeli musicians, and as a resolute critic of the Israeli occupation of Palestinian territories. Barenboim has received many awards and prizes, including an honorary Knight Commander of the Order of the British Empire, France's Legion d'honneur both as a Commander and Grand Officier, and the German Grosses Bundesverdienstkreuz and Willy Brandt Award.

Daniel Barenboim was born in 1942 in Buenos Aires, Argentina, to Argentinian-Jewish parents Aida (nee Schuster) and Enrique Barenboim. He started piano lessons at the age of five with his mother, continuing to study with his father, who remained his only teacher. On 19 August 1950, at the age of seven, he gave his first formal concert in his hometown, Buenos Aires. In 1952, Barenboim's family moved to Israel. Two years later, in the summer of 1954, his parents took him to Salzburg to take part in Igor Markevitch's conducting classes. During that summer he also met and played for Wilhelm Furtwangler, who has remained a central musical influence and ideal for Barenboim. Furtwangler called the young Barenboim a "phenomenon" and invited him to perform the Beethoven First Piano Concerto with the Berlin Philharmonic, but Barenboim's father considered it too soon after the Second World War for a child of Jewish parents to be performing in Berlin. In 1955 Barenboim studied harmony and composition with Nadia Boulanger in Paris. On 15 June 1967, Barenboim and British cellist Jacqueline du Pre were married in Jerusalem at a Western Wall ceremony, Du Pre having converted to Judaism. Acting as one of the witnesses was the conductor Zubin Mehta, a long-time friend of Barenboim. Since "I was not Jewish I had to temporarily be renamed Moshe Cohen, which made me a 'kosher witness'," Mehta recalled. Du Pre retired from music in 1973, after being diagnosed with multiple sclerosis (MS). The marriage lasted until du Pre's death in 1987. In the early 1980s, Barenboim began an affair with the Russian pianist Elena Bashkirova, with whom he had two sons born in Paris before du Pre's death: David Arthur, born 1983, and Michael, born 1985. Barenboim worked to keep his relationship with Bashkirova hidden from du Pre, and believed he had succeeded. He and Bashkirova married in 1988. Both sons are part of the music world: David is a manager-writer for the German hip-hop band Level 8, and Michael Barenboim is a classical violinist.

Problem: 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.

In June 2011, the Beijing Local Taxation Bureau demanded a total of over 12 million yuan (US$1.85 million) from Beijing Fa Ke Cultural Development Ltd. in unpaid taxes and fines, and accorded three days to appeal the demand in writing. According to Ai's wife, Beijing Fa Ke Cultural Development Ltd. has hired two Beijing lawyers as defense attorneys. Ai's family state that Ai is "neither the chief executive nor the legal representative of the design company, which is registered in his wife's name." Offers of donations poured in from Ai's fans across the world when the fine was announced. Eventually an online loan campaign was initiated on 4 November 2011, and close to 9 million RMB was collected within ten days, from 30,000 contributions. Notes were folded into paper planes and thrown over the studio walls, and donations were made in symbolic amounts such as 8964 (4 June 1989, Tiananmen Massacre) or 512 (12 May 2008, Sichuan earthquake). To thank creditors and acknowledge the contributions as loans, Ai designed and issued loan receipts to all who participated in the campaign. Funds raised from the campaign were used as collateral, required by law for an appeal on the tax case. Lawyers acting for Ai submitted an appeal against the fine in January 2012; the Chinese government subsequently agreed to conduct a review. In June 2012, the court heard the tax appeal case. Ai's wife, Lu Qing, the legal representative of the design company, attended the hearing. Lu was accompanied by several lawyers and an accountant, but the witnesses they had requested to testify, including Ai, were prevented from attending a court hearing. Ai asserts that the entire matter - including the 81 days he spent in jail in 2011 - is intended to suppress his provocations. Ai said he had no illusions as to how the case would turn out, as he believes the court will protect the government's own interests. On 20 June, hundreds of Ai's supporters gathered outside the Chaoyang District Court in Beijing despite a small army of police officers, some of whom videotaped the crowd and led several people away. On 20 July, Ai's tax appeal was rejected in court. The same day Ai's studio released "The Fake Case" which tracks the status and history of this case including a timeline and the release of official documents. On 27 September, the court upheld the 2.4 million tax evasion fine. Ai had previously deposited 1.33 million in a government-controlled account in order to appeal. Ai said he will not pay the remainder because he does not recognize the charge. In October 2012, authorities revoked the license of Beijing Fa Ke Cultural Development Ltd. for failing to re-register, an annual requirement by the administration. The company was not able to complete this procedure as its materials and stamps were confiscated by the government.

So what happened to WeiWei after that court decision?
