Hello LZ
The complete plot of cooking wine and discussing heroes can be found in the Romance of the Three Kingdoms.
In the official history of the Three Kingdoms, it is only written that Liu Bei received the Edict on Clothing and Belts, and was then invited to dinner by Cao Cao. During the dinner, Cao Cao suddenly said, "You and I are the only heroes in the world." Liu Bei was so frightened that he dropped his chopsticks. There is no process of cooking wine and specifically discussing heroes except perhaps discussing Yuan Shao! It can be seen in "The Chronicles of the Three Kingdoms and the Chronicles of Shu"
Before the First Lord came out, Dong Chengci, the cavalry general and uncle of Emperor Xian, received the secret edict in the emperor's belt to kill Duke Cao. The First Lord has not yet sent forth. At that time, Cao Gong calmly said to the late master: "Today's heroes are only the envoys and caoer. There are not enough disciples from the beginning." The first master was just eating, but lost his dagger and chopsticks, so he and Cheng and Changshui captain Zhong Editor, General Wu Zilan, Prince Fu and other conspirators. Meeting with envoys, but not sent yet. When things happen, everyone will be punished.
Then green plums are not cooked with wine. The original text of the Romance of the Three Kingdoms is
Put green plums on a plate and boil wine in a bottle
So green plums are a dish to go with wine.
The only wine during the Three Kingdoms period was rice wine, which was unfiltered sake.
