Jiang Taigong's fishing is a historical legend that happened in Shang and Zhou Dynasties. Shang and Zhou Dynasties were autocratic, and Zhou Wenwang was determined to overthrow it. Jiang Taigong Ziya was ordered by her master to help King Wen. But Jiang Ziya felt that he had been half a century, and he had no friendship with King Wen, so it was difficult to gain the appreciation of King Wen. So on the way back to Beijing, King Wen fished without bait with a straight hook on one side of the river. As we all know, the hook is curved, but Jiang Ziya caught a lot of fish with a straight hook (not a hook) without bait. King Wen saw it and thought it was a strange man (the ancients respected him very much), so he took the initiative to talk to him and found that he was really a useful talent, so he confessed. Later, Jiang Ziya helped King Wen and his son overthrow the rule of Shang and Zhou Dynasties and established the Zhou Dynasty. Two-part allegorical saying: Jiang Taigong is fishing-who wants to take the bait?
