can u pls tell me how to take a bus to Beijing nan zhan from airport?? how much the price now??

After your landing, you can walk to take shuttle bus line 10 according to the guiding signs. It will take you to South Train Station directly. The bus fare is CNY16 per person.

The bullet train (Dong Che) to Jianjin costs CNY54.5 for a second class seat and CNY65.5 for a first class seat.

Well, if you wanna travel to Tianjin upon arrival at PEK, there are actually direct buses. It takes around 2.5h and the bus fare is CNY82 per person.
