The age of full criminal responsibility stipulated in our country's criminal law is 16 years old. In addition, eight types of violent crimes such as murder and robbery only require 14 years of age. Those under 14 years of age are not criminally responsible at all. Obviously, not to mention detention centers, even prisons can be entered. Our lawyer has handled a criminal case. The child was 16 years and 3 months old when he committed the crime. The parents thought it was okay regardless of whether they asked. The first trial lasted 3 years and 10 months. The lawyer acted as the attorney for the appeal hearing. The case was sent back to the Intermediate Court and the sentence was changed to 2 years and 10 months. At this time, the child had been in Fenyang Detention Center for more than two months.
