I live in Lao Cai, a rather large city. Lao Cai is very famous for tourism. Despite being famous, there are still some bad things about transportation in Lao Cai. First, the road in Lao Cai is sometimes blocked, which is due to too many vehicles moving on the road. Next, in small towns, there is always a situation where roads are blocked by dirt and rocks. And the most dangerous problem is the erosion phenomenon. I hope Lao Cai will develop more and more.
