Go to Gongbei Port from Baiyun Airport in 13th Jan with 3 adults and 4 children.

Dear Sanggil Kim,

Thanks for your attention on TravelChinaGuide.com! According to your situation, you are not advised to hire a private car because the fare is expensive about this transfer. Thus, it is suggested to take airport shuttle bus and get to Zhuhai Gongbei first. The ticket fare is CNY 88 per person. The trip takes around 3 hours. After arriving, you can just walk to the border. Hope helpful!

Have a good day and kindest regards!
