About 200 people gathered at various locations in Hong Kong to voice their discontent on Monday, a day after police arrested nearly 50 people at a march against mainland Chinese shoppers and parallel traders. Answering online calls, crowds turned up outside the Revenue Tower in Wan Chai, and on streets in Causeway Bay to chant slogans, while some staged a sit-in at the Kowloon Commerce Centre in Kwai Chung. A group of insurance workers and musicians in Kwun Tong set up a street booth to sign people up for their work unions, the Hong Kong Music Industry Union, and the Hong Kong Insurance Union. Anti-government protesters believe being part of a union to be an effective way of protecting themselves during future strikes. In Wan Chai, more than 100 people took part in a march, and a financial planner in his 40s, who would only give his name as Tony, said it was his fourth or fifth lunchtime rally. “We still hang in to the movement, protests have become part of our life,” he said. “You can’t expect tens of thousands of people to show up during lunch time.” About a dozen pro-independent activists joined midway through chanting, “Hong Kong independence, the only way out!” Not everyone joined in with the calls for independence, and Annabelle, an accountant in her 30s, said she did not think it should detract from the main issues. “Everyone is entitled to his own opinion,” she said. “It’s their freedom, but I won’t chant the slogans myself.” A group of students also took part in the march, with Form Five student David Lee leading the rally at one point. The 17-year-old said he supported the idea of independence for the city, and said only by breaking away from China could Hong Kong become truly international. “The police made mass arrests last week again in Causeway and Sheung Shui, if we don’t speak up now, the entire movement will die down. So we must have some activities to maintain the momentum,” he added. Marchers from Wan Chai made their way along Hennessy Road to join another group in Causeway Bay. Together, they walked towards Times Square shopping centre, where they chanted slogans before departing. Hong Kong’s lunchtime protests resurgent as hundreds vent anti-government anger across the city In Kwai Chung, about a dozen people took part in a peaceful sit-in, in the lobby of the Kowloon Commerce Centre, with protesters holding placards. A poster circulated on the internet called for those who attended to wear face masks to prevent “prevalent bacteria”, a reference to the pneumonia outbreak in the central mainland China city of Wuhan, which many fear could spread to Hong Kong. But police and government have accused protesters of wearing masks to hide their identities and, for some, to evade criminality. A law banning people covering their faces was ruled unconstitutional by a Hong Kong court in November. The government’s appeal will be heard on Thursday this week. Monday’s protest came a day after a rally in Sheung Shui ended in chaos. Protesters took to the border town to vent their frustration at parallel traders, both from the mainland and Hong Kong, who buy products in the city and resell them at a higher price across the border. Local residents were also unhappy that many shops in the neighbourhood had been turned into pharmacies and cosmetic shops to cater to mainland shoppers and traders, disregarding their needs. Police began advancing on protesters outside Sheung Shui Centre and arresting them after 4pm, after they said another group of demonstrators had hurled petrol bombs at the Sheung Shui Police Station. But Democratic Party lawmaker Lam Cheuk-ting, who was among the organisers, called the police operation “outrageous”, and said the approved march was due to last until 5pm, and had been conducted in a peaceful and orderly manner.
