In a lifetime of herding, Liu Xiangqing had never seen cows so scared.
Normally, at 6 a.m., they would be gathered together, contentedly chewing and grazing in the dawn light. But this June morning, they were scattered through the pine scrub, pacing with agitation, their ears alert. Liu took a quick head count and realized one was missing, a 2-year-old bull.
By the time the remains were located, the tail and thighs were missing, the entrails spilled in the dirt. There was a gash in the neck; claw marks raked down the torso.
It was a sure sign: The Siberian tiger was back.
