The Minjiang River source is located at a high altitude, but many people don't know about it and not many people go there. Therefore, the air quality is very good, and the mountain scenery is also nice, with blue sky, green grass and clear water. It feels very comfortable there, just like a plateau in the world. However, I don't suffer from altitude sickness, because I have lived on a plateau at an altitude of about 2,000 meters all year round, so I am more adapted to high altitudes. People in plain areas need to pay attention to preventing altitude sickness.
