On the 37th anniversary of the 1989 Tiananmen Square crackdown, police in Beijing warn families of people who died during the military suppression that they will not be allowed to visit graves, according to multiple reports. A person with knowledge of the matter says relatives were told they would be barred from visiting a cemetery connected to the victims on the anniversary. Authorities in Hong Kong have similarly banned a related vigil since 2020, according to reports citing local restrictions. Several outlets describe the warnings and bans as part of broader efforts by Chinese authorities to limit public commemoration of the crackdown and prevent remembrance activities tied to the event. The reporting characterizes this as a continuation of yearslong measures to restrict or discourage public and community-led efforts to mark the anniversary. Across the sources, the central point is that police and related authorities issue warnings and restrictions aimed at preventing families and others from gathering or visiting cemetery sites connected to the Tiananmen deaths during the anniversary period.
