People's Liberation Army General Zhang Yang was found hanged at his Beijing home [npr.org] on November 23:
Xinhua said Zhang had "serious disciplinary violations," something [The South China Morning Post] describes as "euphemism for corruption." NPR's Rob Schmitz, reporting from Shanghai, says the general "had disappeared from public sight more than two months ago amidst a crackdown on corruption within military ranks launched by Chinese leader Xi Jinping."
[...] "Xi Jinping's decision to persecute both Xu and Guo after their retirement reflects his determination to put an end to the dominance of Jiang Zemin (his own patron) over the military. As far as the cleaning up of corruption in the Chinese military is concerned, however, this is just the beginning," The Diplomat wrote at the time Guo [Boxiong] was dismissed [thediplomat.com] from the military in 2015.
