Beneath the cloud cover of these mountains lies a lost world – a haven teeming with rare plants and undiscovered animal species. Laura Bier, the BBC's correspondent in China, filled us in on the incredible sights awaiting those who venture into these sink holes. Local villagers, who once believed these sites were haunted by demons, have been active participants in the exploration efforts, guiding scientists deeper into the caverns.
Upon their entry into these natural wonders, explorers often encounter a fascinating spectrum of flora and fauna, prompting questions even amongst seasoned experts. Many species discovered here are unlike anything researchers have previously encountered, igniting an excitement for the unknown.
