How is this vigil in London keeping the memories of the Tiananmen Massacre alive?

Commemorating Tiananmen Square massacre was banned in China. Now, it's not even possible in Hong Kong anymore. People are left with no choice but to do it overseas to keep its memory alive. PinkHouse Productions present a documentary on the vigils and protests in London on 4th June 2022.
