HOHHOT Nov. 26 (Xinhuanet) -- Passengers at an airport in northern China's Inner Mongolia Tuesday had the good luck to see a wolf run quickly along the runway and then disappear into the grassland nearby.

    The scene happened at Dongshan Airport of Hailar in Hulun Buir City, which is located on the fringe of grassland.

    In the past, groups of wolves roamed the area and the local government encouraged residents to kill them because they attacked livestock, according to an old man who had worked in the city for many years and once killed four wolves in 40 minutes.

    As a result, the number of wolves decreased sharply and the ecological chain was destroyed.

    In recent years, the local government abolished the policy and took a series of measures to protect the wild animals, resulting in an increase in numbers. Enditem
