"In August 2015, zookeepers at the National Zoo in Washington, DC, were thrilled to spot a tiny shadow on an ultrasound. For a species as rare as the giant panda, every new cub is cause for celebration. Zoo staff monitored mother Mei Xiang, and within days a newborn appeared, weighing in at just one third of a pound. While Mei Xiang cradled her vulnerable infant, zookeepers monitored the pair day and night through cameras in the panda den, and some two million viewers logged on to the zoo website. First Ladies Michelle Obama and Peng Liyuan hosted a ceremony to announce the cub's name: Bei Bei, meaning "precious treasure" in Mandarin Chinese. An instant celebrity, the cub captured hearts all over the world. But pandas in zoos are considered emissaries from the People's Republic of China, the only country where they live in the wild. Four years after his birth in America, Bei Bei would embark on an important new mission."--Provided by publisher.
