Yan Hong is the son of Empress Xuan and the king of Yiqu. In the TV series "The Great Qin Empire", before marrying Qin Huiwen and Wang Ying, Duck Bazi met the lonely Prince Yiqu, and they had a son Ya 'an. The TV series "The Great Qin Empire" takes Shang Yang's burial of Qin Zhen to crush the old aristocratic rebellion as the breakthrough point, which is closely connected with the first part, and begins to tell the tortuous story of the stable and powerful Qin State's eastward entry into the Central Plains, the joint resistance of Shandong six countries to Qin, and the division of Qin and Lian Heng among the six countries.
