A friend of mine was detained on suspicion of illegal possession of guns. I want to ask you what kind of punishment he will have.

According to the law, if your friend is suspected of illegal possession of guns, he will violate the provisions of Article 128 of the Criminal Law of People's Republic of China (PRC) on gun management and be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance. If the circumstances are serious, they shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years.
