3 June 2014 Last updated at 23:15 BST
It is 25 years since Chinese authorities crushed a popular movement for democracy in their capital city, Beijing.
Among those protesting was 18-year-old student Haoyu Zhang.
He spoke to the BBC about his memories of early June 1989.
Witness is a World Service radio programme of the stories of our times told by the people who were there.
