King Wen detained Zhouyi and asked for the historical story of this sentence.

King Wen interpreted the Book of Changes when he was in prison. Zhou Wenwang, whose real name is Ji Mingchang (BC1213-117), was called Xibo in history. He was the leader of the Zhou people in the late Shang Dynasty. He is charitable, develops production and wins the support of the people. This aroused the suspicion and dissatisfaction of Shang Zhouwang (later called Yin). He listened to rumors foolishly and brutally, and imprisoned Ji Chang in the national prison at that time-Youli City. After Ji Chang was imprisoned, Yin insulted and tortured him by various barbaric means, and even killed his eldest son and made him swallow it. Ji Chang was imprisoned for seven years, and he turned Fuxi's inherent gossip into gossip.
