Problem: Chen Guangcheng (born 12 November 1971) is a Chinese civil rights activist who has worked on human rights issues in rural areas of the People's Republic of China. Blind from an early age and self-taught in the law, Chen is frequently described as a "barefoot lawyer" who advocates for women's rights, land rights, and the welfare of the poor. He is best known for accusing people of abuses in official family-planning practices, often involving claims of violence and forced abortions. In 2005, Chen gained international recognition for organising a landmark class-action lawsuit against authorities in Linyi, Shandong province, for the excessive enforcement of the one-child policy.

On 7 September 2005, while Chen was in Beijing to publicize his class action lawsuit against the Linyi city family planning staff, he was reportedly abducted by security agents from Linyi and held for 38 hours. Recounting the incident to foreign journalists, Chen said that authorities threatened to levy criminal charges against him for providing state secrets or intelligence to foreign organizations. After Chen refused negotiations with local officials to cease his activism, Linyi authorities placed him under effective house arrest beginning in September 2005. When he attempted to escape in October, he was beaten. Xinhua, the news agency of the Chinese government, stated that on 5 February 2006, Chen instigated others "to damage and smash cars belonging to the Shuanghou Police Station and the town government" as well as attack local government officials. Time reported that witnesses to Chen's protest disputed the government's version of events, and his lawyers argued that it was unlikely he could have committed the crimes due to his constant surveillance by police. Chen was removed from his house in March 2006 and was formally detained in June 2006 by Yinan county officials. He was scheduled to stand trial on 17 July 2006 on charges of destruction of property and assembling a crowd to disrupt traffic, but this was delayed at the request of the prosecution. According to Radio Free Asia and Chinese Human Rights Defenders, the prosecution delayed the trial because a crowd of Chen supporters gathered outside the courthouse. With only a few days' notice, authorities rescheduled Chen's trial for 18 August 2006. On the eve of his trial, all three of his lawyers, including Xu Zhiyong of the Yitong Law Firm, were detained by Yinan police; two were released after being questioned. Neither Chen's lawyers nor his wife were allowed in the courtroom for the trial. Authorities appointed their own public defender for Chen just before the trial began. The trial lasted only two hours. On 24 August 2006, Chen was sentenced to four years and three months for "damaging property and organizing a mob to disturb traffic". As a result of Chen's trial, British Foreign Secretary Margaret Beckett selected his case for the cover of the British government's 2006 human rights report, stating concern over the handling of Chen's case and calling for the Chinese government "to prove its commitment to building rule of law." A Globe and Mail columnist also criticized the verdict, writing that "Even assuming [Chen] did damage 'doors and windows,' as well as cars, and interrupt traffic for three hours, it is difficult to argue a four-year prison sentence is somehow proportionate to the offence." On 30 November 2006, Yinan County court upheld Chen's sentence, and on 12 January 2007, the Linyi Intermediate Court in Shandong Province rejected his final appeal. The same court had overturned his original conviction in December 2006, citing lack of evidence. However, Chen was convicted in a second trial on identical charges and given an identical sentence by the Yinan court. Following the trial, Amnesty International declared him to be a prisoner of conscience, "jailed solely for his peaceful activities in defence of human rights".

Problem: Sir Richard Starkey (born 7 July 1940), known professionally as Ringo Starr, is an English musician, songwriter, singer, and actor who gained worldwide fame as the drummer for the Beatles. He occasionally sang lead vocals, usually for one song on an album, including "With a Little Help from My Friends", "Yellow Submarine", "Good Night", and their cover of "Act Naturally". He also wrote the Beatles' songs "Don't Pass Me By" and "Octopus's Garden", and is credited as a co-writer of others, including "What Goes On" and "Flying". Starr was twice afflicted by life-threatening illnesses during childhood, and he fell behind in school as a result of prolonged hospitalisations.

When Starr married Maureen Cox in 1965, Beatles manager Brian Epstein served as best man, with Starr's stepfather Harry Graves and fellow Beatle George Harrison as witnesses. Soon afterwards, the couple's matrimony became the subject of a US novelty song, "Treat Him Tender, Maureen", by the Chicklettes. Starr and Maureen had three children together: Zak (born 13 September 1965), Jason (born 19 August 1967) and Lee (born 11 November 1970). In 1971, Starr purchased Lennon's former home, Tittenhurst Park at Sunninghill in Berkshire and moved his family there. Following Starr's repeated infidelities, the couple divorced in 1975. Maureen died from leukaemia at age 48 in 1994. In 1980, while on the set of the film Caveman, Starr met actress Barbara Bach; they were married on 27 April 1981. In 1985, he was the first of the Beatles to become a grandfather upon the birth of Zak's daughter, Tatia Jayne Starkey. Zak Starkey is also a drummer, and during his father's regular absences, he spent time with The Who's Keith Moon. Zak has performed with his father during some All-Starr Band tours. In total, Ringo Starr has eight grandchildren - one from Zak, four from Jason and three from Lee. In 2016, he was the first Beatle to become a great-grandfather. Starr and Bach split their time between homes in Cranleigh, Surrey; Los Angeles; and Monte Carlo. In the Sunday Times Rich List 2011, Starr was listed at number 56 in the UK with an estimated personal wealth of PS150 million. In 2012, Starr was estimated to be the wealthiest drummer in the world. In 2014 Starr announced that his 200-acre Surrey estate at Rydinghurst, with its Grade II-listed Jacobean house, was for sale. However, he retains a property in the London district of Chelsea off King's Road, and he and Bach continue to divide their time between London and Los Angeles. In December 2015, Starr and Bach auctioned some of their personal and professional items to the public via Julien's Auctions in Los Angeles. Highlights of the collection included Starr's first Ludwig Black Oyster Pearl drum kit; instruments given to him by Harrison, Lennon and Marc Bolan; and a first-pressing copy of the Beatles' White Album numbered "0000001". The auction raised over $9 million, a portion of which was set aside for the Lotus Foundation, a charity founded by Starr and Bach. In 2016, Starr expressed his support for the United Kingdom's withdrawal from the European Union, explaining: "I thought the European Union was a great idea, but I didn't see it going anywhere lately." In 2017 he described his impatience for Britain to "get on with" Brexit, declaring that "to be in control of your country is a good move."
