Meng De went to Jiangnan, what does fortune telling mean?

Meng De was Cao Cao in the Three Kingdoms period. Xiajiangnan obviously refers to when Cao Cao crusaded against Sun Quan of Soochow, Sun Quan of Soochow and Liu Bei of Xishu jointly crusaded against Cao Cao, which is the famous battle of "burning Red Cliff" in history. Cao Cao was defeated and returned. Since then, I dare not face up to Jiangnan. And what you said is what the fortune teller said. It is a quotation, which means that what you want to do will not succeed. Although you may not like this sentence, this is the actual situation. Tell the truth, tell the truth.
