The creative background of Looking at the Sea;

Wuhuan was a great disaster in Northeast China at that time. In the 11th year of Jian 'an (2006), Wu Huan invaded Youzhou and captured more than 100,000 Han people. In the same year, Yuan Shang and Yuan, the sons of Yuan Shao, colluded with Ta Dun, the leader of Wuhuan in western Liaoning, and repeatedly harassed the border, so that Cao Cao had to resolutely decide to conquer Wuhuan in the 12th year of Jian 'an (207). Later, under the guidance of Tian Chou, he used tricks.

Cao Cao finally won a decisive victory in the great war in August this year. This victory consolidated Cao Cao's rear areas and laid the foundation for the next year's conquest of the south, with a view to realizing the grand aspiration of reunifying China. "Looking at the Sea" is about the time when Wu Huan, who won the Northern Expedition, crossed Jieshi Mountain and returned to Li.
