Border Mongolia-China

It is in the top 1 of the most surreal things I've ever seen. Passing the border of these 2 countries by road is crazy. 1st in Mongolia you should rent a car, a kind of ramshackle road. The price is $ 10 per person. In August we got that car plus a driver. The driver went like crazy skipping checkpoints,and the police chase him. After the stop, and upon payment of a few dollars behind the car, we keep going. The tail is incredible, and the distance between cars is 1 cm. The cars hit each other, in the queue. At one point, our driver goes, and gets someone else to drive. Later the 2nd driver who came out of nowhere goes.
