Hong Kong–Zhuhai–Macau Bridge
In November 2018, shortly after the opening of the Hong Kong–Zhuhai–Macau Bridge, a large number of tourists from mainland China stayed in Tung Chung district, leading to complaints of local residents about overcrowding. Yiu said that he had asked the Security Bureau to instruct the police to arrest illegal mainland tour guides who had not worked with the legally required Hong Kong liaison.
