In this episode of "The Mammoth Task," staff members of the Yuxi Public Security Bureau in southwest China's Yunnan Province share their experiences with the northward-trekking elephant herd. Members of the bureau's unmanned aerial vehicle (UAV) monitoring team said they could feel the connection with these animals. "The baby elephants are like our own children, and they are not here to disturb our lives," one staff member said. "It's like a family visit."
