text: In 1966 the Cultural Revolution began and Liu was sent to work, where he was tasked with cleaning and digging sewage ditches and other unskilled work. In July 1966, Liu Shaoqi was denounced as a "capitalist roader" and "traitor", and was removed from his position as Party Deputy chairman by Lin Biao.
  As a consequence of the downfall of his father, Liu Yunbin was also condemned as a "spy" and "capitalist roader". He was beaten and abused by the Red Guards, who took him to an urban area in Baotou, where he was publicly humiliated at a denunciation rally. On 21 November 1967, Liu committed suicide by lying on the rails on the railway north of the residential area where his family lived.
  Liu's father died on 12 November 1969, in Kaifeng, Henan, due in part to maltreatment and torture in custody. Following the end of the Cultural Revolution in 1976 with the death of Mao Zedong, Liu Yunbin was posthumously rehabilitated and his reputation restored in 1978. In the same year, a solemn memorial service was conducted for him at the 202 Factory Club. Liu Shaoqi was posthumously rehabilitated in 1980.
  On 16 April 2015, Russian Ambassador to China Andrey Denisov awarded the Jubilee Medal "70 Years of Victory in the Great Patriotic War 1941–1945" to 32 Chinese citizens, including Liu Yunbin, who was posthumously awarded the medal.
