Mao ZedongÂ’s last surviving son, Mao Anqing, who suffered from mental illnesses and worked as a Russian translator, has died in Beijing at the age of 84, the official Xinhua agency reported late on Saturday. Born in southern Hunan province, he was smuggled to Shanghai by the communist underground in 1930 after Nationalist officials killed his mother Yang Kaihui, Xinhua said. But together with elder brother Mao Anying, he was often left to fend for himself on the cityÂ’s streets and was once beaten by a policeman which contributed to later mental problems, Chinese media reported. Mao Anqing is survived by photojournalist wife Shao Hua and son Mao Xinyu - born in 1970 at the height of ChinaÂ’s cultural revolution that Mao Zedong launched to boost his fading power.
