Ex-Politburo committee member He Guoqiang makes rare public foray
He Guoqiang dropped by a school while his own son is investigated by the authorities

He Guoqiang, a former top government leader whose son is being investigated by authorities, made a rare public appearance on Wednesday.
He visited a Confucius school in Guiyang in Guizhou province. The visit echoed an earlier one by President Xi Jinping to a Confucius institute in Shandong province in November.
He Guoqiang’s appearance … must be approved by the top leadership
Top leaders in the Communist Party, including Xi, sanctioned a corruption investigation into He's eldest son, He Jintao , the South China Morning Post reported last month.
Four separate sources told the Post that the senior He had not been implicated in the case.
He Guoqiang, 70, was formerly head of the party's anti-corruption commission and a member of the elite, nine-man Politburo Standing Committee under general secretary Hu Jintao .

Retired government leaders rarely appear in public, but a series of former top officials have returned to the spotlight in recent months.
