The troops advanced into central parts of Beijing on the city’s major thoroughfares in the early morning hours of 4 June and engaged in bloody clashes with demonstrators attempting to block them, in which many people – demonstrators, bystanders, and soldiers – were killed.

Here's a video of an interview with Chai Ling recorded on May 28, 1989 with reporter Philip Cunningham. Chai Ling was arguably the most influential leader of the student protesters at Tiananmen Square. In the interview she openly wishes for the soldiers to massacre the students after her instrumental role in blocking attempts by other activists to move the protest back to campuses, all while refusing to sacrifice herself.

Notable quotes from this interview include:-

"You, the Chinese are not worth my struggle. You are not worth my sacrifice"

"The students keep asking what shall we do next? What can we accomplish? I feel so sad, because how can I tell them what we're actually hoping for is bloodshed - for the moment when the government has no choice but to brazenly butcher the people?"

"Only when the square is awash with blood will the people of China open their eyes. Only then will they really be united"

"If we allow the [protesters] movement to collapse on its own, then the government will be able to wipe out all the leaders of the movement"

Upon being asked if she will stay in the square herself after urging the students to stay she simply responded, "No, I won't".

When the Tiananmen Square incident erupted in violence on June 3rd, Chai Ling escaped from Beijing by train. She was eventually smuggled to Hong Kong via Operation Yellowbird, an MI6/CIA led initiative to extract dissidents who they hoped would form the nucleus of a "Chinese democracy movement in exile". To my knowledge, no details exist about how and when she made contact with them. She was subsequently invited to study at Princeton on a full scholarship due to her pivotal role in the Tiananmen protests. She studied Politics and International Relations there, eventually picking up an MBA from Harvard. Today, she runs an internet company called Jenzabar that she founded with her husband, the lawyer Robert Maginn, a long time associate of the Republican party, having even served as the chairman of the Massachusetts Republican party between 2011 and 2013. Their company serves more than 1300 higher education institutions worldwide, whom they provide with ERP software.
