Langdu Wetland Grassland is located in the transition zone between the eastern section of the Qinghai-Tibet Plateau and the western edge of the Qinling Mountains in Minxian County, with a plain and hilly terrain. The average altitude here is 2,600 meters, the terrain is flat and open, the climate is cool and pleasant, there are crisscrossing rivers, vast grasslands and beautiful scenery. Unfortunately, the weather was bad, the rain was getting heavier and heavier, and the road was becoming more and more difficult to walk on. We had to return with a sense of regret. The original plan was to go to Shuangshimen Scenic Area, but we had to give up because of the rain. The most depressing thing when traveling is probably encountering continuous rain. Starting from Long County and heading south, you will pass through the Qinling Mountains along the way. There are mountains and gurgling rivers, and beautiful scenery everywhere you look. It was already noon when we arrived at Langdu Wetland. After walking out of the mountains, we suddenly saw a vast expanse of space in front of us, and I felt a sense of sudden enlightenment. According to legend, a long time ago, there was abundant grass and water here, and there were many wild animals. Wolves often came here to look for food and drink water, so the beach got its name Langdu Beach.
