Following the development of infrastructure in the reserve in recent years, Tang Yulin's patrols have become more manageable. The golden snub-nosed monkeys have also grown accustomed to closer human interaction, with more than 140 research monkeys successfully relocated to lower-altitude areas near rivers, where they now thrive.

Today, the reserve boasts the highest density of these monkeys in the country, making it a prime location for observing them in the wild. Inspired by Tang Yulin's dedication, his nephew Tang Xiaogang joined the ranks of forest rangers in 2019, becoming a fourth-generation guardian of the lush mountains and its monkeys.
