Entering early winter, the mountains and rivers of Changning County, Baoshan, are dyed with warm colors. The golden ginkgo and the orange-red metasequoia complement each other, like a poetic painting. Under the warm winter sun, the ginkgo leaves are spread on the ground, shining with golden charm; near the Ginkgo Avenue, the leaves of metasequoia are turning from emerald green to deep red, like a burning flame, making the winter particularly charming.
