The annual July 1 march took place in Hong Kong on Sunday to mark the 21st anniversary of Britain’s handover of the territory to China in 1997. The march, an important barometer of public sentiment in Hong Kong, has suffered from dwindling participation over the past few years, with turnout down again this year. The organizer, the Civil Human Rights Front, said 50,000 people attended, while the police put the figure at 9,800 — either way, they are the lowest figures on record.
