For the past 20 years, Bao Mingwei has been caring for Southwest China’s wild Asian elephant population. When he came across an injured young elephant, which he named Longlong, he faced a problem. Although Longlong wasn’t badly hurt, at just two months old he hadn’t yet been weaned. Elephant’s milk is unique in its composition. But based on his lengthy experience, “Elephant Doctor” Bao Mingwei was able to come up with a substitute to feed to Longlong.
