【明報專訊】PASSENGER FLOW on the Hong Kong-Zhuhai-Macao Bridge (HZMB) has reached a new high, with tour groups from the mainland cropping up at Tung Chung on two consecutive weekends. As some of these tour groups were neither approved by the mainland authorities nor registered with the Travel Industry Council of Hong Kong, it is suspected that they were irregular. Since the opening of the HZMB, the SAR government has been focusing on the prevention of traffic congestion without giving much thought to how the surge in people will put a strain on the Tung Chung community. Such a lack of consideration has caused chaotic scenes one after another. Not only are complaints from Tung Chung residents everywhere, but tourists also think that they are paying for an unenjoyable experience. The government must discuss the matter of irregular tour groups with the mainland authorities as soon as possible. It should, at the same time, come up with ways to divert the crowds and upgrade the ancillary facilities so as to reduce the strain on the community. Otherwise, new conflicts between China and Hong Kong might be triggered.
