I think Li Laohan's behavior is illegal, because while we enjoy the right to life and health, we have the moral obligation and legal obligation not to infringe on the right to life and health of others. No one may illegally deprive others of their lives, even if they are loyal to their families, because this is an act of violating the right to life; No one may intentionally or negligently cause injury or illness to others, because this is an act that violates the right to health.
We should care for all beings, care for the lives and health of others, stay away from violence, and be a law-abiding and helpful person.
