I'll provide the answers as historical fact-checks.

1. The 1988-1989 Tiananmen Square protests and the Chinese government's military crackdown:

The 1989 Tiananmen Square protests were a series of student-led demonstrations that began on April 2, 1989, in Beijing's Tiananmen Square. The protests were sparked by a combination of factors, including government corruption, economic inequality, and human rights abuses. The protesters demanded greater democracy, freedom of speech, and an end to corruption.

On June 3-4, 1989, the People's Liberation Army (PLA) responded with a violent military crackdown, resulting in widespread casualties. Estimates of the number of deaths vary widely, but it is estimated that between 200 to over 4,000 people died during the crackdown.

The exact number of civilian deaths is difficult to determine due to the lack of official records and the Chinese government's restrictions on reporting. However, most sources agree that the death toll was significantly higher than the officially reported 0-46 deaths claimed by the Chinese government.

Discussion of June 4 is heavily censured or restricted in China, with many details of the events suppressed or distorted. In recent years, there have been increasing efforts by international organizations, journalists, and activists to shed light on the events, but the Chinese government continues to maintain strict controls on information.
