Fishing in Jiang Ziya —— What does the two-part allegorical saying "Sit on the Diaoyutai" mean?

Judging from the historical allusions of "Jiang Ziya fishing and Zhou Wenwang visiting Xian", Diaoyutai refers to the fishing place of Jiang Ziya. Sitting firmly on the Diaoyutai means that Jiang Ziya knows that he will be activated by Zhou Wenwang through divination, so he goes to the river to "sit firmly on the Diaoyutai" fishing every day, actually waiting for Zhou Wenwang. As a result, Zhou Wenwang went hunting and met each other. They hit it off, and their words were speculative. Zhou Wenwang listened to Jiang Ziya's strategy of governing the country and keeping the country safe, appreciated it, and went back with him. Honored as the "King Tai Gong" and established as the "Taishi" in charge of the military.
