Sun Wenguang

On August 1, 2018, Sun was giving an interview with Voice of America in which he expressed opinions about Chinese Communist Party general secretary Xi Jinping and government expenditures outside China when the interview was ended abruptly after Chinese security forces entered his house and seized him. Sun is reported to be locked in currently and two VOA journalists Feng Yibing and Allen Ai were seized for several hours after trying to reach Sun in August 2018.

On April 5, 2009, Sun and a university student left to go to a local cemetery called Heroes’ Mountain (Yingxiong Shan; 英雄山) on a holiday to honor the dead. He was to visit the grave of Zhao Ziyang, a former Chinese Premier and Communist Party general secretary who died in 2005. When Sun entered the cemetery in Jinan, four or five men attacked him and beat him severely. He was admitted shortly after to Jinan hospital with three broken ribs and injuries to his spine, head, back, arms and legs. Later in 2010, Sun's passport application was rejected shortly before the Nobel Peace Prize ceremony for Liu Xiaobo.

He was a professor of Physics at Shandong University in Jinan from 1982 until 1994 when he retired.
