You've seen shepherd dogs, but Wu Yonglin, a guardian of the Przewalski's gazelles who has been working in Qinghai Lake National Nature Reserve, has a "shepherd gazelle".

Wu has devoted himself to conservation work since the early 2000s. His work does not only include monitoring the gazelle's population, but rescuing wounded or lost gazelles, conducting artificial breeding and even being a "super daddy" of calves.

Unlike most gazelles which keep a certain distance from humans, Dong Dong, one of the calves rescued and raised by Wu, is like a "shepherd gazelle." She follows Wu to check her herd's safety whenever he comes patrolling. Check the video to learn more! 

About 'Yes! Sir'

Until 2018, China had more than 2,700 nature reserves in which countless protection stations had been established. And now, China has made major strides in building national parks to protect the environment as well as the biodiversity. "Yes! Sir" is a new series by CGTN Nature. We visit those protection stations and learn about the stories of those working on the front line of nature conservation.
