Join Bubble Bamboo, a fluffy giant panda, on his journey to reunite with childhood friends. In this episode, Bubble Bamboo visits the wetlands of Northeast China to help a shy red-crowned crane blend into the flock and express itself. Native to these vibrant ecosystems, red-crowned cranes rely on healthy wetlands to survive. Thanks to years of conservation efforts, both these majestic birds and their habitats are now being steadily protected. (Produced by Cheng Weidan, Wang Zi, Li Zhuoman and He Jiahao)
