Xu Zhangrun

Xu Zhangrun (; born October 1962) is a Chinese jurist. He was a professor of Jurisprudence and Constitutional Law at Tsinghua University in Beijing, and a research fellow with the Unirule Institute of Economics. His dissident writing having previously caused retributions by the authorities, in July 2020 he was detained for a week and subsequently barred from leaving Beijing. Observers believed this to be the result of an essay in which Xu sharply criticized the management of the COVID-19 pandemic in China under Paramount leader Xi Jinping.

Education Xu received his bachelor's degree from the Southwest University of Political Science and Law, a master's from the China University of Political Science and Law, and in 2000 a PhD from the University of Melbourne.

Research Xu's research specializes in jurisprudence, Western legal philosophy, constitutional theory, and the relationship between Confucianism and law. He is the author of a book on the Australian legal system. The essay has been translated into English by Geremie Barmé. That essay received some commentary from Western scholars. Xu had been suspended and put under investigation. The article proposed to restore the Chinese Chairman's tenure system, namely, from the life tenure system instituted under Xi's rule on 11 March 2018 to the fixed-term system that perdured between 1982 and 2018. The article prompted discussion among Chinese people about the changes. Some supported it, while some were worried about the safety of Xu. The article was published at a time of tension in China, which included the China–United States trade war as well as reports of inner-conflicts among senior Chinese Communist Party officials. The article emphasized that the public, including bureaucratic officials, were concerned about personal safety issues as well as the direction of national development. Xu claimed that these fears were due to the breaking of four basic principles by the ruling class, namely, public security, respect of private property, tolerance of the population's life freedoms, and the term limit in political governance.

Detention In April 2019, friends reported that the authorities had prohibited Xu from leaving the country. He was stopped from boarding a flight to Japan on a trip authorized and funded by Tsinghua University. He was defended by other intellectuals, such as Zi Zhongyun, whose 2019 essay, "Mourning Tsinghua", attacked the action of Tsinghua authorities as the "latest round of 'book burning and burying scholars'".

In February 2020, Xu published an essay, "Viral Alarm: When Fury Overcomes Fear", condemning the Chinese government's response to the COVID-19 outbreak. Xu describes how the government banned the reporting of factual information during the outbreak and connects this problem to a larger freedom of speech issue in China. being accused of speaking critically about China's response to the COVID-19 pandemic. He was released from custody on 12 July 2020. Subsequently, Xu was fired from his job at Tsinghua University. Both the US State Department and High Representative of the Union for Foreign Affairs and Security Policy Josep Borrell, who mentioned Xu in connection with the 709 crackdown, said that the EU:

Following his arrest, Xu was blacklisted by vendors, and after his release, he was put on an online blacklist which barred him from receiving donations from the public. In September 2020, artist and book vendor Geng Xiaonan was arrested together with her husband, ostensibly on charges of illegal business activities, but Xu said it had been because she had spoken out in his support. He put himself at the forefront of an effort by Chinese dissidents to publicize the difficulties of the couple.

In an essay published in December 2020, Xu wrote about his experience of being permanently monitored by security cameras in his compound in Beijing; while remaining free, he was not allowed to leave the city.
