The future emperor wanted to be a prince, and was always pestering Su Wu, wanting to learn from him. The civil and military ministers of the DPRK all knelt down when they saw Su Wu. Then one day, Su Wu was not in a good mood, so... Su Wu stood in front of Emperor Jiaqing and asked: "Your Majesty, if you sign this, your surname will be Su in the world, and you can completely cultivate immortality."
