咬人 (yǎo rén): to bite someone

This puppy is usually very gentle, but if you take its food, it will bite people.

Mom said, don't casually touch strange dogs in the park, to avoid being bitten.

That cat, because it was scared, hid under the bed and bit anyone who came near.

After the child was bitten by a mosquito, a red swollen bump appeared on the skin.
