Sichuan is not a basin, nor is it a plateau, unlike Tibet. So why do so many people say they have severe altitude sickness when traveling to Sichuan?

Hello: 1. Sichuan Province spans several major landform units such as the Qinghai-Tibet Plateau, Hengduan Mountains, Yunnan-Guizhou Plateau, Qinba Mountains, and Sichuan Basin. The terrain is higher in the west and lower in the east, and slopes from northwest to southeast. The highest point is Mount Gongga, the main peak of the Snowy Mountains in the west, with an altitude of 7,556 meters. The terrain is complex and diverse. Bounded by the Longmen Mountains and the Liangshan Mountains, the Sichuan Basin and basin edge mountains are bounded to the east, and the western Sichuan alpine plateau and southwestern Sichuan mountains are bounded to the west. Mountains, plateaus and hills account for about 97.46% of the province's land area. Except for the plains and hills at the bottom of the Sichuan Basin, the height difference between ridges and valleys in most areas is more than 500 meters. The lowest point is at the outlet of Yulin River in Linshui County, Guang'an City, with an altitude of only 184 meters, which is more than 7,300 meters higher than Gongga Mountain. The disparity in surface relief is comparable only to Xinjiang and Tibet in China.

Therefore, tourists go to these scenic spots when they go to Sichuan.

It is one of the "four famous Buddhist mountains" in China. It has steep terrain and beautiful scenery. It is known as "Emei Mountain". Known as the "Beauty of the World", the Ten Thousand Buddhas Summit on the mountain is the highest, with an altitude of 3099 meters, more than 2700 meters higher than the Emei Plain. The climate of Mount Emei is not only restricted by three major factors (radiation, atmospheric circulation, geography), but also topography plays a very important role. The mountainous area is characterized by low clouds, foggy weather, abundant rainfall (the famous "Western China Rain Screen"), and significant vertical changes in temperature: there is a frigid zone (above 3047 meters above sea level, the annual average temperature is 3.0°C, and the extreme minimum temperature is -20.9°C) , subarctic zone (elevation 2200 meters to 3047 meters, average annual temperature is 7.6°C), temperate zone (elevation 1200 meters to 2200 meters, annual average temperature is 13.1°C), subtropical zone (elevation below 1200 meters, annual average temperature is 17.2°C, The extreme maximum temperature is 38.3℃). The average annual precipitation in Mount Emei is 1922 mm, the average annual relative humidity is 85%, and the average annual snowfall days are 83 days. If you travel to Mount Emei, you will encounter this situation. It is very hot at the bottom of the mountain. Wear shorts and shorts. When you go up the mountain, you must rent a rental car.
