One of Beijing's cemeteries holds a dark secret. In eight graves lie urns with the ashes of young men. They died in a hail of bullets on the night of June 4, 1989, when the army put down student protests at gunpoint. The police only allow their parents and relatives to visit these graves. The massacre is taboo. In Hong Kong, the traditional candlelight service planned for today in Victoria Park has been banned, as it was in 2020. The cemetery is the only place in China where remembrance still has a public place.
