From the New York Times (link):
One of the many unexpected things about the small graveyard here where Xi Qingsheng buried his mother during the mayhem of the Cultural Revolution is that it still exists.
The rusted front gate, locked for many years, opens into a walled cemetery that amounts to a time capsule from an era the Communist Party wants to forget. Revolutionary slogans, long since discredited, are etched onto huge, ornate tombstones, including the large concrete marker that Mr. Xi built for his mother when he was a teenager.
“It is my obligation to speak about this history,” said Mr. Xi, now 54. “It is the Communist Party’s crime. Of course, they don’t want to talk about it. No one wants to talk about shameful things.”
