A joke about the word ran ..

The ancients spoke very succinctly and skillfully. For example, one said "Ran". I remember a monarch of Qi asked his military adviser a question. The strategist nodded and smiled and said, "Of course." Then the monarch went back and pondered for a long time whether this "ran" was for or against, and as a result, he broke down from constant overwork. Before he died, he told his adviser the answers he had considered and asked him if he meant it at that time. The strategist smiled and said, "Of course." The emperor died soon.
