In short, if you injure someone in a fight in China, everything depends on the injury level certified by forensic doctors: a minor injury means a criminal case under Article 234 of the Criminal Law with up to three years in prison; serious injury means three to ten years; and causing death or extremely serious harm can mean ten years to life imprisonment or even the death penalty. Fights that cause only slight harm are public security violations punished with short detention and fines.

The three levels under Article 234

Article 234 of the Criminal Law punishes intentional injury. Where the victim suffers a minor injury, the penalty is fixed-term imprisonment of up to three years, criminal detention or public surveillance. Serious injury carries three to ten years in prison. Causing death, or causing serious injury by especially cruel methods that leaves the victim seriously disabled, carries ten years to life imprisonment or the death penalty. The decisive fact is the forensic injury certificate, not how the fight felt at the time.

When it is not a crime: administrative detention

If the injury is below the criminal threshold, the police handle the case under the Public Security Administration Punishments Law: the usual results are administrative detention of five to fifteen days and a fine, on top of compensation for the victim’s medical costs. Foreigners should take even these cases seriously — an administrative penalty can still hurt visa renewals, and a criminal conviction for intentional injury normally means a criminal record and, for foreign offenders, often deportation after the sentence under Article 35 of the Criminal Law.

What this means in practice

Mutual fights are investigated differently from one-sided attacks: the police look at everyone who used violence, so “he started it” is not a defence by itself. Genuine self-defence under Article 20 — responding with roughly proportionate force to an unlawful attack that is actually happening — can stop a case, but it is assessed strictly once the fight is over. For minor-injury cases the police routinely encourage mediation: compensating the victim and obtaining a written understanding is the single strongest factor for a lighter outcome or having the case dropped, though it is not an automatic right.

Hypothetical example: after a late-night argument in a Shanghai bar, a visitor punches another customer and breaks his nose. If the forensic report classifies the fracture as a minor injury, the visitor faces a criminal case under Article 234 — with compensation and a clean record, a suspended sentence is the typical result. If the report finds only slight harm, the case stays administrative: usually about five to ten days’ detention and a fine, plus the medical bill.

The bottom line: in China the injury certificate decides whether a punch becomes a criminal record or just a fine — and the cheapest time to call a lawyer is before you give the police your statement.
