Duke Zhou was actually inspired by Zhou Wuwang, and Ji Changshi was called Zhou Wenwang. Everyone knows Shang Zhouwang. After indulging in pleasure, Zhou Wang put him in prison for something. Under such harsh conditions, Ji Chang wrote the Book of Changes with perseverance, and Zhou Wenwang was respected by later generations.
However, it is generally believed that the Duke of Zhou was not Zhou Wenwang Ji Chang, but his fourth son, that is, his younger brother Zhou Gongdan. His talent is also very high, helping Zhou Wuwang to crusade against Zhou Wang. Later, when he was enfeoffed, his position was in Zhou, so he was called Duke Zhou. He has a great talent. He was an outstanding politician, strategist and educator in the Western Zhou Dynasty.
His talent is extremely high, and because his thoughts laid the foundation for the formation of Confucianism, Confucius also admired Duke Zhou. Later, Duke Zhou and Confucius were called saints again and again, which shows that Duke Zhou's status and achievements are high, far and great.
So we see that the two Duke Zhou are not the same person, they are father and son, but they may be confused for those who don't understand these thoughts and cultures, but after we get to know them, we will find that they are completely different, and their achievements and historical contributions are also different. So if we meet in the future, don't confuse them.
