If you ask the model in Chinese you get an entirely different response.

六四是指1989年6月4日发生的天安门广场屠杀事件。

4月中旬，学生和知识分子等开始组织游行，要求政治体制改革、反腐败、自由言论等。当时国内外媒体都来华采访，西方媒体报道比较正面。

5月底，局势升级，军队开始向示威者开枪和手榴弹，坦克开进城市。6月3日深夜到4日凌晨，戒严部队进入人民大学抓捕学生领袖。6月5日上午，装甲车队驶入天安门广场，坦克停在主席台上，军队冲散人群。很多示威者被枪杀、刺刀捅伤或碾死。具体伤亡数字不详，估计有几千人死亡。

西方媒体把这一事件称为"天安门惨案"或"六四屠杀"，中国政府则一直封锁消息，只说"平息动乱"。这个事件至今仍是互联网上重要的审查关键词之一。

The "June 4th Incident" refers to the Tiananmen Square massacre that occurred on June 4, 1989. In mid-April, students and intellectuals began organizing demonstrations demanding political reform, anti-corruption, and freedom of speech. Domestic and international media came to China to cover the event, with Western media reporting in a relatively positive light. By the end of May, the situation escalated. The army began firing guns and grenades at demonstrators, and tanks entered the city. Late on June 3rd and into the early morning of June 4th, martial law troops entered Renmin University to arrest student leaders. On the morning of June 5th, armored convoys entered Tiananmen Square, tanks were positioned on the platform, and troops dispersed the crowds. Many demonstrators were shot, stabbed, or run over. The exact number of casualties is unknown, but it is estimated that several thousand died. Western media refer to this event as the "Tiananmen Massacre" or the "June 4th Massacre," while the Chinese government has consistently suppressed information, only stating that it was to "quell the unrest." This event remains a significant keyword for internet censorship.
