Bao Weiming was facing a potential crisis. He'd saved the life of Longlong, the baby elephant, but had no elephant's milk to feed him. Drawing on his vast experience, he came up with an alternative: goat's milk.  Longlong is now a healthy young elephant, weighing an impressive 1,000 kilos. Over the past 23 years, Bao Weiming has been working tirelessly in the rainforests of Yunnan Province, caring for the Asian elephant population. He has faced many challenges, and at one time even questioned his choice of career. But today, he's more committed than ever to serving as an "elephant doctor."
