Xiezi Mountain in Jinan, East China's Shandong province, is divided by its ridge, with the northern slope covered with pine and cypress trees, and the southern slope with cotinus coggygria. As autumn progresses, the leaves of the cotinus coggygria transform from green to red, creating a unique landscape of two colors on one mountain.
