Legal analysis: Whether the nasal bone fracture is a minor injury or not, the national judicial department has clear provisions on the injury identification. If the nasal bone fracture is a comminuted fracture or linear fracture with obvious dislocation, or if the fracture has obvious influence on facial morphology or nasal function after reduction, it will achieve minor injuries. In addition, I want to explain the difference between minor injuries and minor injuries. Minor injuries constitute a criminal offence in public security control. If it is a minor injury, it is not a criminal offence, but a matter of civil compensation. Therefore, we must grasp a very accurate scale in judicial injury identification and conduct injury identification according to law. Because if the perpetrator constitutes a minor injury, he will be sentenced to prison. If it is only a minor injury, it does not meet the standards of criminal law, but a civil dispute.

Legal basis: Article 234 of the Criminal Law of People's Republic of China (PRC) intentionally hurts another person's body, and he shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance.

Whoever commits the crime mentioned in the preceding paragraph and causes serious injuries shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years; Whoever causes death or serious disability by particularly cruel means shall be sentenced to fixed-term imprisonment of not less than 10 years, life imprisonment or death. Where there are other provisions in this Law, such provisions shall prevail.
