Can the plaintiff defend himself without a lawyer?

Of course, the suspect can defend himself without a lawyer. The Criminal Procedure Law stipulates that criminal suspects have the right to defense. In addition to self-defense, relatives and friends such as lawyers of criminal suspects can act as defenders, provided that their personal freedom is not restricted. However, self-defense has great limitations. Article 11 of the Criminal Procedure Law of People's Republic of China (PRC), the trial of cases by the people's courts shall be held in public, except as otherwise provided in this Law. The defendant has the right to be defended, and the people's court has the obligation to ensure that the defendant is defended.
