Wikipedia indicates there wasn’t a massacre in Tiananmen square: “Several people who were situated around the square that night, including former Beijing bureau chief of The Washington Post Jay Mathews[f] and CBS correspondent Richard Roth[g] reported that while they had heard sporadic gunfire, they could not find enough evidence to suggest that a massacre took place on the square”

“In 2011, three secret cables from the United States embassy in Beijing agreed there was no bloodshed inside Tiananmen Square.[244] Instead, they said Chinese soldiers opened fire on protesters outside the square as they fought their way from the west towards the center.[244] A Chilean diplomat who had been positioned next to a Red Cross station inside the square told his US counterparts that he did not observe any mass firing of weapons into the crowds in the square itself, although sporadic gunfire was heard. He said that most of the troops who entered the square were armed only with anti-riot gear.”

While they do provide sources that say the student death toll was likely high, most sources estimate over 500.

I’m just trying to be factual- the students were funded and supported by Western forces including the United States, probably not to help the students and spread democracy and capitalism, but to create division. The students clashed with China’s fucked up communist government and military. There’s not too many possibilities when a civilian force clashes with a state military.
