2. There are regular taxis, and the price is around 30 yuan (it seems that the last time I took a taxi was around 28 yuan), but there are basically black cars at the entrance of the North Station, so you have to walk to the road to see a regular taxi.
3. If you are not in a hurry, you can take bus No.21or 12 at the East Square of Langfang North Station (go straight along the wall after leaving the ticket gate and turn right at the intersection), and you will arrive. It takes about 50-60 minutes. Ticket price, 2 yuan. (Free ride at present)
