Join Bubble Bamboo, an adorable fluffy giant panda, in celebrating International Day for Biological Diversity, which falls on Friday. In this series, our cuddly adventurer treks across vast plateaus, lush grasslands, and winding rivers to reunite with his childhood buddies through their matching friendship badges. This episode features his heartwarming rendezvous with a Tibetan antelope on the first leg of his journey. Native to the Qinghai-Xizang Plateau, Tibetan antelopes were once an endangered species. Thanks to decades of relentless conservation efforts, their population has bounced back to over 300,000. (Produced by Cheng Weidan, Xu Zheqi, Zhang Jian and Lu Dong)
