Showdown, I Am the Ming Emperor Zhu Yuanzhang

Mu Xing traveled to the Ming Dynasty and opened a tavern. There are two regular customers in the tavern, one named Lao Zhu and the other named Lao Xu. What Mu Xing didn't expect was that Lao Zhu's true identity was Zhu Yuanzhang, while Lao Xu was Xu Da. Lao Zhu: "The shopkeeper is full of poems and books. Wouldn't it be a pity to be a shopkeeper? Why not serve as an official in the court and make contributions?" Mu Xing: "Being an official? Oh, even dogs are not qualified to be officials in the Ming Dynasty."
