About CGTN Nature

North China's Shanxi Province lies quietly on the Huangtu Plateau, also known as the Loess Plateau. The midstream of the Yellow River, China's mother river, flows through here. The Yellow River had been nourishing this vast land of loess for thousands of years, cradling not only the rich Chinese culture, but also numerous wildlife species and mesmerizing geological wonders. The 10-episode Yellow River Series presents a glimpse of the region's special terrain and native wildlife.
