Shanghai | Tens of thousands of people were preparing to gather in a Hong Kong park on Tuesday to remember those killed in the 1989 Tiananmen Square crackdown,  in what will be the only public recognition within greater China of the massacre in Beijing 30 years ago.

The anniversary has been notable for the collective amnesia in China around the violent state reaction to protests which, it is thought, took the lives of thousands of students and onlookers. The  current generation of students in China are either oblivious to the events of 30 years ago or too scared to talk about it in public.
