Gongbei seems to start at eight o'clock? I haven't been there for a long time. Almost every time you go through customs in Zhuhai and Wanchai, you only need to queue up a few times. But it takes 10 yuan to cross Macau by boat. You can also go back by boat from Macao. At 4 o'clock at the latest, there are far fewer people than Gongbei. Queue up to 10 minute. At least, there are almost two or three people waiting in line. There is no queue after the customs.
