Since joining the branch in 2017, Li has become Zhao's work partner and apprentice. After seven years' cooperation, they have patrolled in extreme cold and protected the pristine forests of the northern Greater Hinggan Mountains.

"I have spent years here in the company of these forests. I know where the flowers bloom, where the birds sing, and where the deer roam. I know when the stars shine the brightest, and I see the wildlife and plant life flourishing. It fills me with immense pride," Li says.

Over the years, forest police officers like Zhao and Li have made significant contributions in guaranteeing the region's environmental conservation.
