From Thursday to Sunday, over 484,900 passengers and 68,700 vehicles, both inbound and outbound, passed through the port, as reported by the border inspection station of the HZMB, the world's longest bridge-and-tunnel sea crossing.

During the period, the total number of Hong Kong tourists exceeded 280,000, making up about 59 percent of the total passenger flow, with a daily peak reaching 80,000, according to the inspection station.
