Ex-hunter goes from top killer to protector

Early one morning, before sunrise and before nature has awoken, 59-year-old Liang Feng'en walked calmly through the forests in Suiyang town, Heilongjiang province, carrying his green-and-black GPS device, a camera, a diary and a medical kit.

Decades ago, Liang was a well-known hunter in the region, but he now works as a ranger for Suiyang's forestry bureau, applying his knowledge to aid wildlife conservation in the country's northeast.

His main duty is to find and record the tracks of wild Siberian tigers and their prey, such as deer and boar, which is essential work for big-cat protection.
