I am a native of Jiangmen. I plan to take the light rail from Jiangmen City Rail, go to Gongbei, Zhuhai, and then travel to Macau to find a route.
Jiangmen Light Rail Station: Guzhen Station-Jianghai Station-Jiangmen Station-Lille Station-Xinhui Station. Choose the nearest station and take the light rail to Zhuhai North Station (at Jinding). Then take bus 3A to Baotelai Science and Technology Station. You can transfer to CR Vanguard at the bus stop between Huazishi East Station and 10 or 10A, and get off at Gongbei Port.
