China is the country with the richest variety of azaleas in the world, with over 160 species along the 318 National Highway. Rhododendrons prefer damp and cold environments, and their presence can be found from high mountains to near ice and snow circles. Dujuan Gorge, also known as Qianpu Gorge, is the opening scene of the movie "New Kangding Love Song". It is a glacial moraine river formed by glacial action, spectacular and wonderful. At the turn of spring and summer, alpine rhododendrons bloom enthusiastically. The Rhododendron Gorge is 8 kilometers long and has 68 species of rhododendrons. They start blooming at an altitude of 2800 meters and continue to bloom until reaching the top of Mount Mugecuo at 3800 meters. Among them, May and June are the most spectacular, with various colors of azaleas such as red, pink, yellow, and white opening up the Dujuan Gorge into a sea of azaleas. When it snows, you can see the magnificent scene of snow crushing the azaleas, and snowflakes gather on the azaleas, which can be said to coexist in spring and winter. So when spring arrives in Kangding, who makes the decision? The crowd sees the azaleas, and the azaleas in Kangding are praised for their stunning beauty. Dujuan Gorge is also a long corridor of azaleas along National Highway 318.
