Get off at Nanning Railway Station and there will be a bus to Beihai.

Ticket price, 50 yuan.

You don't have to go to Langdong or Jiangnan, it's far from Nanning Railway Station.

And the price is similar.

Last time I went to Beihai, I took a bus at night.

I don't know the earliest. The 9: 30 p.m. flight should be the last one.

It takes two hours to get to Beihai.
