On the side of the road in the Hoh Xil Nature Reserve in Qinghai Province, you might see a fat wolf. It wags its tail in front of the passing cars. It hopes to get a meal. 

However, the wolf was skin and bones a few months ago. It’s said that the old hungry wolf was forced to leave the wolf pack (群体) because it was not good at hunting (猎食). But that all changed after a passing driver gave it two pies and posted a video of it online. The video made the wolf very popular, and a lot of people came to the area to provide it with food.

Since then, the wolf has given up its hunting instinct (本能) and turned to passers-by for snacks. The snacks are high in oil, sugar and salt, such as pies, roasted chicken and sausages. Later, more wolves have joined this behavior. The wolf’s change makes it look like a pet dog. But the change means that it is losing its ability to live in nature, and that may cause the wild animal to die.

In fact, it is common for wild animals like wolves and bears to be fed near the roads in the province. People care about wild animals, but their feeding sometimes can cause harm to both animals and themselves. If a wild animal needs help, people are suggested to report it to the government for professional handling (专业处理).
