During last week's commemoration of the 30th anniversary of the June 4 Tiananmen Square massacre, eyewitnesses described feelings of deep sadness and grief for lost hope and youth. For Canadian sinologist Diana Lary, this was especially true, because most of her adult life had been tied to China. "June 1989 for me was one of the saddest and most painful periods of my life," she said of China's military crackdown using tanks and guns to kill hundreds, possibly thousands, of pro-democracy student protesters in Tiananmen Square in Beijing.
