Detian Waterfall is worth visiting, but Tiangong is not beautiful, it rains, China and Vietnam take the river as the boundary, China is rich and strong, we have a lot of tourists here, looking at Vietnam only sparse tourists, seeing Vietnam's shops, like poor people's simple tents, I feel more and more proud of being a Chinese. To the border monument 53 of China and Vietnam, I buy a lot of food, durian cake, dried mango, cashew. Self-driving to Detian Waterfall, to the only parking lot do not buy any sightseeing ticket 45 yuan, that is similar to the bus to send you to the scenic spot, about 15 minutes, there is no scenery on the road, just along the river, the river is opposite Vietnam, in fact, you can drive directly to Detian Waterfall.
