not sure what has this to do with hacking/IT, but

Tiananmen square massacre is mislabeled event, more people died in other parts of Beijing than average in the square, so more appropriate name would be Beijing massacre or what Chinese use 6/4.

People who died in square were pretty much suicidal since they were warned to leave and were told to leave even by their own protester leaders.

It should be always mentioned that wife of current hard liner president Mao 2.0 She Gin Pimp was singing at that time to murderers in square.

Overall not sure why are media so obsessed with this event were few thousand people died instead or mentioning millions who died thanks to glorified Mao. It's pretty good trade-off with DXP for most of the Chinese compared to trade-off gained with Mao.
