What are the personality characteristics of Ji Fa in West Zhou Wuwang?

Before the Battle of Makino, Zhou Wuwang once called governors to crusade against the Shang Dynasty, but when the time came, he went back on his word and said, "The time has not come." Let it go this time. The second time, Zhou Wuwang ordered the wizard to perform divination, and the result was unlucky. If Jiang Ziya hadn't dropped his shell and said, "What does this dead turtle know?" And insisted that the king of Wu wage war, it is estimated that this time it will be yellow.

After the battle of Makino, King Wu destroyed the Shang Dynasty, and he still lamented at night: "Alas, there are so many adherents of the Shang Dynasty, what should we do?" Jiang Ziya advocated killing them all, Duke Zhou advocated "goodness", and King Wu adopted the method of Duke Zhou. However, the adherents of Shang Dynasty are still alive after all, and they may still rebel, just because they are afraid that the adherents of Shang Dynasty will rebel, which scared King Wu to death-three years after the demise of Shang Dynasty, King Wu died.
