He was sentenced to eight years in prison in December 2017 for subversion of state power, and is currently incarcerated in Qingliu Prison in Fujian. Human rights activities Wu has been involved in human rights activism since May 2008 when he supported the woman charged with murder in the Deng Yujiao incident. Since then he has advocated online and on the streets for a number of human rights cases, using provocative T-shirts, banners and performance art to highlight the cases he fights for. In one case he drew a Hitler moustache on the photo of the chief judge, along with a demand to know what bribe he would accept. In spring 2015 Wu started working for the Beijing Fengrui Law Firm, but on 20 May 2015 he was detained by police in Nanchang, and on 7 July he was formerly arrested and charged with inciting subversion of state power, and then in 16 August he was charged with subversion of state power. In August 2017, after two years in detention, Wu was put on trial in Tianjin, charged with subversion of state power. On 26 December 2017 he was found guilty and sentenced to eight years in prison, which is one of the harshest sentences given to a Chinese human rights activist since the start of China's crackdown on lawyers and activists in 2015. On 4 January 2018, Ge Yongxi one of Wu Gan's lawyers, confirmed that Wu Gan has filed an appeal against his 8-year sentence. In addition to the appeal, Wu Gan petitioned the Chinese judiciary to ask that the National People's Congress either amend or nullify subversion-related charges and punishments as stipulated by article 105 of the nation's Criminal Law. On 8 November 2018, while he was in prison, all of the 30,277 tweets made by Wu Gan between November 2009 and May 2015 (up to when he was arrested and so stopped tweeting) were deleted by a bot. Wu's father, Xu Xiaoshun (), visited his son at Qingliu Prison in Fujian in early March 2019, and reported that Wu Gan was suffering from poor health and a possible spinal injury
