King Wu conquered the Shang Dynasty and became the king of the world. He granted his teacher Shangfu the title of Duke of Yingqiu in Qi. The old city of Yingqiu was originally divided into "outer city", "inner city" and "imperial city". The imperial city, now the Gucheng Village, is about 100 miles long and wide. In front of the village stands a village monument of "Gucheng". The inscription records the origin, history and deeds of the ancient city, and a section of the ruins of the imperial city stands in the northwest corner of the village. Jiang Taigong was the founder of the State of Qi, the founding hero of the Western Zhou Dynasty, the founder of Qi culture, and an outstanding strategist, military strategist and politician with a long-lasting influence in ancient China. His historical status has been recognized in the classics of all dynasties. Confucianism, Taoism, Legalism, Military, Yin-Yang, and Vertical and Horizontal Schools all regard him as their own figure and are respected as the "Master of Hundred Schools". As a religious god, he is a god of war and wisdom, and is regarded as a guardian deity of "Taigong is here, there are no taboos". To this day, in many places in China, especially in the surrounding areas of Changle, the custom of using "Taigong is here" as a talisman to suppress evil and exorcise monsters and bless peace is still widely popular.
