Hong was also charged with being unable to account for the sources of his property totalling 31 million yuan, according to the Guiyang Intermediate People's Court.

He also served posts such as deputy county government head, economic development and industrial park zones' directors and deputy head of Qiandongnan prefectural government during the period.

In another case, Shu Xi, former Communist Party boss of Hongjiang City in the central Hunan Province, was put on trial on Monday and Tuesday at a court in Hunan.
