Joshua and Sophia open the first chapter of Romance of the Three Kingdoms with a lively dialogue, telling the background of the Yellow Turban Rebellion and the story of Liu Bei, Guan Yu, and Zhang Fei's oath of brotherhood in Taoyuan. It shows the social environment of the late Eastern Han Dynasty, where political corruption and people's livelihood were in dire straits, which eventually led to the peasant uprising. The three brothers became sworn brothers because of their common ideals - to support the Han Dynasty and pacify the world. They fought bravely and made great achievements, laying the groundwork for the subsequent Three Kingdoms. At the same time, Cao Cao's early image was also shown, foreshadowing his fate of being a powerful figure in the future.
