You Promised to Be a Salted Fish, but You Became the Master of the Ming Emperor?

Traveling through the Hongwu period of the Ming Dynasty, Zhu Qinghe just wanted to be a salted fish waiting to die, and by the way he adopted a little amnesiac beggar as his son. Zhu Qinghe taught him how to calculate accounts, talk about economics, tell him "Tokyo Dreams", and even told him the story of compound interest between the king and the chessboard. As a result, the old farmer next door (Zhu Yuanzhang) squatted in the corner and eavesdropped every day! Zhu Qinghe said that Ming Dynasty treasure banknotes should be abolished, and he made sense; Zhu Qinghe said that the vassal king was a beast that swallowed gold and he would be afraid; Zhu Qinghe said that the future emperor might have to borrow money from ministers, and he was so frightened that he cried on the spot! Later, he insisted on giving Zhu Qinghe a seal of King Wu, and also wanted to take the emperor's grandson back? Zhu Qinghe: Lao Zhu, don't bother me, I really just want to lie down!
