A black bear in a wildlife zoo in Weihai, Shandong Province, has quite a taste for alcohol. But what amazes zookeepers most is that it knows when to stop drinking before it becomes drunk.

The 10-year-old bear likes drinking beer - it can down a bottle of beer in just a few seconds. After finishing one bottle, the bear will fold its paws into a bow, indicating to zookeepers that it wants more. But as soon as it finishes a six-pack, the bear will stop drinking no matter how hard the keeper pushes it to having more.
