Wang Wei 王威

In Chapter 34 of the Romance, when Liu Bei, having come to Xiangyang, is to entertain the officials from every quarter in place of the ailing Liu Biao, Cai Mao consults Kuai Yue and means to do away with Liu Bei on that occasion. Kuai Yue says that Zhao Yun never leaves Liu Bei's side whether walking or sitting, so it will be hard to strike, and proposes having the two men Wen Pin and Wang Wei set up a separate table in the outer hall to entertain the military officers, keeping Zhao Yun there first and then carrying out the deed; Cai Mao follows this advice. Romance, Ch. 34 §34–37

On the day of the banquet, as Zhao Yun stands at Liu Bei's side wearing his sword, Wen Pin and Wang Wei come in and invite Zhao Yun to his seat. Zhao Yun declines and does not go, but when Liu Bei tells him to take his seat, he reluctantly obeys and goes out. While Cai Mao surrounds the outside tightly and waits for the wine to take hold, Yi Ji tips off Liu Bei, and Liu Bei flees alone through the west gate on his horse Dilu. Romance, Ch. 34 §38–40

In Chapter 41, when Cao Cao at Fancheng sends men to summon Liu Cong, who has surrendered, Liu Cong is afraid and does not dare to go, and Cai Mao and Zhang Yun offer to go instead. Wang Wei secretly tells Liu Cong that since the general has already surrendered and Xuande has also gone, Cao Cao is sure to relax and take no precautions, and that if he lays a surprise force in ambush in difficult terrain and strikes, Cao Cao can be captured. If Cao Cao is captured, his might will shake the realm, and however vast the Central Plains, they can be pacified with a single proclamation, so this rare opportunity must not be lost. Romance, Ch. 41 §20–21

When Liu Cong tells Cai Mao of this, Cai Mao rebukes Wang Wei, asking how he dares to talk so recklessly when he does not know the Mandate of Heaven. Wang Wei angrily retorts, 'You traitor who sells out the state! I regret only that I cannot eat your flesh alive!', and when Cai Mao wants to kill him, Kuai Yue stops him. Romance, Ch. 41 §21

Liu Cong and his mother Lady Cai cross the river and greet Cao Cao with obeisance, but Cao Cao makes him Inspector of Qing Province and has him set out at once. When Liu Cong, with no choice, leaves for Qing Province with his mother, only the old general Wang Wei goes with them, and the other officials all see them off as far as the river mouth and return. When Yu Jin, on Cao Cao's orders, pursues them with light cavalry and shouts that he has come to kill mother and son, Wang Wei, enraged, fights back with all his strength but is finally killed by the many soldiers. The soldiers kill Liu Cong and Lady Cai, and Cao Cao richly rewards Yu Jin. Romance, Ch. 41 §25–28
