A good dragon Tianxian! I thought that the so-called Tianxian was just a scenic spot with a gimmick. I found that it was really hard on the road. It turned out that the national road passed a section of the perennial rocky mountain road through Bomi. This is really dangerous. Parking first, listen first, pray first, and then drive to pay attention to safety!

Pailong Tianxian, with the completion of Pailong No. 1 Bridge and No. 2 Bridge, no longer exist. However, along the Nu River, the mountain structure looks very loose, and it should be maintained continuously during the rainy season.

Pailong Tianxian is no longer a ghost gate. Due to geological conditions and road maintenance, this has always been a bowel obstruction on the Sichuan-Tibet line. Few cars arrive here without queuing. It is a common thing to block for a day or two. I was lucky when I first left, because there was a car falling into the river in the morning, so many cars did not dare to continue to go, I only queued for about half an hour. Now that the road has been replaced by a tunnel, the road conditions are so good that I have a little nostalgia for the thrilling old road.

The long dragon sky insurance is 14 kilometers long, with narrow, rotten, dangerous characteristics, known for the steep world. Due to the loose and fragile mountain, when the wind and rain or ice melt, it is easy to occur mudslides and landslides, resulting in traffic disruption; Even in the dry season, due to the crush of large cars, the road ruts are serious, the stones are all over, and the cars often wipe the bottom when passing by. If you are lucky, it takes an hour to walk the 14 kilometers in a good weather.

Passing the Tongmai Bridge, it is the most precipitous section of the Sichuan-Tibet line. It is known as the "death section" of the Pailongtian Risk. This is the most dangerous section of the Sichuan-Tibet line. Between Bomi and Nyingchi, the length is 14 kilometers. The road is only one car wide. During the rainy season, it often landslides or mudslides. In addition, the road rut is serious, the car often supports the bottom when passing, and it takes more than an hour to walk these 14 kilometers smoothly. It is the only way to go on the Sichuan-Tibet line. It is estimated that after the bridge and tunnel are built next year, the traffic situation will be greatly improved.
