First, read the English article below.

It's normal for puppies to bite as they develop and grow. Usually, they learn about not biting from other members of their pack, including adult dogs. Puppies learn by playing with other pack mates about when to avoid causing serious damaging through biting. If puppies don't learn to control or stop biting, the other dogs will punish the puppy more severely, possibly by biting the puppy to cause injury. If the puppy does learn easily from his pack mates, they'll become more forceful and clear about biting behavior until the puppy behaves in a manner acceptable to other members of its pack. If you allow puppy biting, it may get out of control and your puppy will not learn to control his bite. This can lead to serious behavioral issues when your puppy reaches adulthood. If you suspect your puppy is biting out of fear or anger, talk with an animal behavioral therapist, who may be able to help. It is not acceptable for puppies to bite people, or other animals, unless they are in true physical danger and need to defend themselves. If you're starting a training program with the help of a qualified trainer, consider muzzling your puppy with a basket muzzle. Your puppy will quickly learn to stop nipping or biting with the help of the muzzle, but muzzling is not recommended if you don't have a clear understanding of the training approach and goals. If the muzzle isn't introduced and used properly, your puppy can actually become more dangerous to people, especially those trying to put the muzzle on the puppy.  Rewarding the puppy by giving it a treat after wearing the muzzle can help the dog associate the muzzle with something good. This makes it less likely to be wary of you or aggressive, and it makes the whole process easier for both you and the dog. Never leave children unattended and unsupervised with dogs, even ones that seem “safe”. You may need to isolate the dog and/or crate him when a knowledgeable adult cannot be present.
