What's the sentence for stabbing a person to death in an argument?

It is believed that the man Cui has been spying on his girlfriend Ren and had an argument with her. After that, Zhang and Cui took out their knives and stabbed each other. In the end, Zhang was stabbed to death and Cui was charged with intentional homicide. After hearing the case, Beijing No.3 Intermediate People's Court held that Cui's behavior constituted a crime of intentional homicide and sentenced him to death with a two-year suspension.

The victim claimed that Zhang was her boyfriend. On the afternoon of August 25th, 20 15, they ate in a restaurant in Miyun, and Zhang drank beer. In the evening, they walked home together and met an unknown Cui, who kept looking at himself and whistling to himself. Zhang was a little angry and said to Cui, "What are you looking at?" Cui still looked at himself and Zhang and shouted, "I'll go and see what's wrong?" Subsequently, there was a dispute between the two sides. Cui took out his knife and stabbed Zhang several times, and then stabbed him several times.

The court held that the evidence in this case can prove that Cui and the victim fought with a knife after quarreling over trivial matters, and both of them were injured in the process. After Zhang lost his ability to resist, the illegal infringement on Cui had stopped. Cui continued to stab Zhang's back several times with a knife, and stabbed him with a knife to dissuade him, and did not commit illegal infringement. In the end, the Third Intermediate People's Court held that Cui constituted a crime of intentional homicide and sentenced him to death with a two-year suspension.
