Hong Kong’s second ban on an annual vigil for victims of the bloody June 4, 1989, crackdown on Beijing’s Tiananmen Square protest movement and the closure of a museum dedicated to the event may be a further sign that the ruling Communist Party is extending its efforts to erase the event from the collective consciousness from the mainland to Hong Kong.
