The vigil, an annual occurrence since the event, is the largest that it has been in years, thanks to clear weather, increased frustration over Hong Kongers' desire for universal suffrage, and an increased interest from the younger generation.Thanks to relaxed visa restrictions between Hong Kong and the mainland, many mainland Chinese people made the trek specifically for the event. China has banned any mention of the Tiananmen crackdown and has put police out in force to prevent any commemoration. "A lot of my friends my age are planning to come to Hong Kong for the vigil," a man from China's Yunnan province told Businessweek. "The younger generation are mostly unaware of what happened. The China we knew back then as youths is very different from the China today."
