Wild Swans had, how shall I put it, a bit of the Attenborough treatment to the film Ghandi, if you get my gist. Life and Death is up a magnitude and is unbelievable that man/woman can do this to a fellow human, more psychological than physical.
As I mentioned, I worked out there. One of my team, well his father had been Surgeon General of Shanghai, his mother also a doctor. They were deemed bourgeoise and executed; their two boys dispatched to work the "night soil" in deepest Sichuan (Szechuan alt sp). If you do not know what night soil is then a google.
That wasn't the real torture though; they were returned to Shanghai in late 69 to work in a steel works, pulling rail carts of steel bars around the yard. His bro died in an open zinc bath, he was left with a permanently arched back. He was one of the few to talk openly about the Cultural Revolution - I had to have a quiet word with him to separate his political demos (and I said understandable) away from the office as he could be putting his colleagues at risk.....horrendous though as you probe away at this awful story of Chinese Human Rights, sadly still ongoing as you may have seen in the press or on TV recently
