This episode offers a glimpse of how Zhu Xinpu, director of the People's Hospital of Maqin County in Guoluo Zang Autonomous Prefecture, northwest China's Qinghai Province, strives to provide the people of Maqin County with a more comfortable and convenient medical environment.
In the hinterland of the Qinghai-Xizang Plateau, the protection of wild herbs, an important source of traditional Chinese medicine, is especially vital. Starting in the sunrise and returning in the twilight, Zachengnan and his teammates walk through the vast forests and grasslands every day to protect the distribution areas of rare herbs.
Guoluo, the cradle of the Yellow River and the land of a thousand lakes, is the kingdom of the plateau's endemic wildlife. Generations of guardians of the headwaters, ranging from doctors and policemen to ecological rangers, stick to the original aspiration of coexistence between man and nature.
