From the plain to the mountainous area, the train just gallops on the great plain, which is covered with trees and is a fertile land for Ma Pingchuan. Unconsciously, the train has entered the depths of the mountains, the railway is no longer straight, there are more and more corners, and the speed is gradually slowing down. There are mountains, mountains, bridges and tunnels one after another. There are thousands of canyons and valleys, and there are towering cliffs and bottomless abyss everywhere. The altitude is getting higher and higher, and the broad-leaved forest is no longer at the foot of the mountain, but gradually becomes a mixed forest of broad-leaved trees and conifers. Soon, all of them became coniferous forests, with pines and cypresses everywhere. Suddenly, a large area of bright pink came into view on the hillside ahead. It turned out to be a blossoming peach tree, which is simply amazing! It can't help but remind people of the poem "The beauty of the world is in April, and the peach blossoms in the mountain temple begin to bloom".
The scenery of the plains and mountains is in sharp contrast.
