The Tiananmen Mothers, a group led by Ding Zilin, a retired professor whose teenage son was killed in the crackdown, called for the Standing Committee of the National People’s Congress to open a dialogue and to investigate the killings. The letter was released through Human Rights in China – a New York-based NGO.
For 19 years, the subject remains taboo and the Chinese government has repeatedly rejected Tiananmen Mothers’ calls to overturn its verdict.
