In response to my follow-up email asking if I could speak to him on the phone about his experience:
Hi, Ben:
For around 40 years since our persecution during the cutural revolution, my wife and I have never talked for once about our experiences then. It is too traumatic to stir up the memories. She prefers forgetting about it and doesn't want to do anything, which I understand. Therefore, she doesn't know about what I did with [a civil rights organization], [an American politician], and now you. If you give me your phone number, maybe I can call you late at night in my bedroom. That means after 11:30 PM if you don't mind.
