"It is learned that the still-closed Lo Wu and Huanggang Boundary Control Points between Hong Kong and Shenzhen may resume operation in early February . . . However, officials of the Immigration Department said at a press conference yesterday afternoon that there was no clear timetable for the resumption of services at Lo Wu Point."
