Tiananmen Square in the Chinese capital Beijing was under heavy security on June 4.

S/ Voice of Mori Hazuki, NNN correspondent “We are right by Tiananmen Square, and security is tight. In recent years, surveillance systems have improved, and there is a possibility of being marked just by driving a car through the square.”

35 years ago, the Chinese government violently suppressed the pro-democracy movement by students in Tiananmen Square, resulting in numerous casualties.

Speaking about the Tiananmen Incident is considered taboo in China, and the authorities are also tightening control over speech related to the incident.

S/ Chinese local: I have no intention of taking the initiative to find out.

“Do you know about the Q64 incident?”

S/Chinese local: “I don’t quite understand what you mean.”

“It was reported in the news at the time,”

S/Chinese local: “That’s enough.”

A woman whose 19-year-old son was shot in the head and killed at the time spoke to us.

She still displays a photo of her son taken two months before his death.

S/ Zhang Xianling: I want to tell young people about the tragedy of the government using the military to suppress the people.”

She says she wants to pass on the memory of the incident to the younger generation, but the Chinese authorities are tightening control, such as banning all memorial services in mainland China and Hong Kong this year as well.
