How did the court hear the Gansu man's complaint of "innocence" after serving his sentence for ten years?

After the first trial in Lanzhou Intermediate People's Court, Zhang, as the principal offender, was finally sentenced to life imprisonment in Lanzhou for intentional injury, and several others were sentenced to fixed-term imprisonment respectively. Zhang Gang, who has been serving his sentence for ten years, is always pleading not guilty. What injustice has made him refuse to accept commutation again and again, and choose to study law in prison and then appeal for his rights?

In the early morning of October 9, 2112, Zhang Gang from Lanzhou, Gansu Province went home with his companion He Mou, but was beaten by five people, including Qu Moumou. For defensive purposes, Zhang Gang stabbed Chang Mou in the neck with a knife, resulting in Chang Mou's death. Because of a minor parking incident, such a major criminal incident happened, Zhang Gang finally appealed, arguing that his behavior was self-defense and the law stipulated that it was legal. However, the Gansu Provincial High Court sent him back for retrial and rejected his appeal.

Zhang Gang has been complaining in prison for ten years, believing that this sudden incident happened without any emotional enmity between himself and the other party. Zhang Gang claimed that he stabbed the other side only in self-defense, and also lodged a protest with the People's Procuratorate, demanding that a retrial be initiated and he be acquitted. His just act was also helped by many people. The prison guards contacted the criminal defense team for him to appeal. After receiving his help, well-known law lawyers also agreed to provide him with legal aid. Lawyer Xiao Zhie and lawyer Li Renzheng became attorneys.

Everything comes to him who waits. At present, the incident has received a reply from Gansu Provincial People's Procuratorate and decided to accept the incident. Xiaobian thinks that the essence of this matter is? Is it right or not? A behavior, in the face of the evil people with knives who have the intention of hurting themselves, it is unreasonable to make them lose their ability to take the initiative to protect themselves if they don't take up arms to resist. The court needs to reopen the case, and treat all aspects of the case as a whole. It should not only see the stage when Zhang Gang hacked and killed five people, but also see that the beginning of the case was provoked by several other people. The court needs to reopen the case and pay attention to some details of the case.
