It is  about that heart wrenching time ago...even though this year marks the 20th anniversary of the June 4th event, I don't feel there is any difference from the same time of any other year.  For my generation, this is something you don't need people to remind you or tell you, it's been engraved into our bones and deeply penetrating into our memories.   When a government turns its deadly weapons toward its own people, its legitimate of governing ends at the very first moment of bullet leaving the barrel. 

Kate Adie Returns to Tiananmen Square will be on BBC Two at 9pm on Wednesday 3 June 2009.
