Because this portrait is of Zhu Yuanzhang, and not only Zhu Yuanzhang's portrait was hung, but also Zhu Yuanzhang's spiritual tablet was hung. It was definitely impossible for Zhu Di to open fire on his father, so he had no choice but to retreat in the end. This is also a major stain in Zhu Di's life, although he is indeed more suitable to be emperor than Zhu Yunwen.

Because Zhu Yuanzhang passed the throne to his grandson Zhu Yunwen at that time, Zhu Di had coveted the throne for a long time and wanted to take the throne from his nephew Zhu Yunwen. At that time, Zhu Di attacked Jinan City during his campaign. The city defender Tie Xuan he met was a person Zhu Yuanzhang valued very much, and he was later assigned to Zhu Yunwen.

Zhu Di surrounded the city of Jinan. He had people shoot portrait books with arrows into the city. Tie Xuan, the general who was guarding the city at that time, also shot an article out of the city. This article talks about After King Wu of Zhou died that year, his younger brother Zhou Gongdan had been helping King Wu's young son to act as regent. When his son grew up, he returned the power to him. In comparison, Zhu Di not only failed to help his nephew stabilize the world, but even wanted to take away his throne.

Later, when Zhu Di attacked Jinan City again, they wanted to use artillery to attack the city wall. At this time, the city defender took out Zhu Yuanzhang's portrait and hung it on the wall. He also placed Zhu Yuanzhang's spiritual tablet on the wall. On the city wall, Zhu Di could not continue to attack his father's portrait and could only choose to retreat. Tie Xuan has a strong character, loyal to protect his master, and has the demeanor of a general. Later, Zhu Di occupied the capital and conquered Jinan. He issued a wanted order to arrest Tie Xuan. In the end, Tie Xuan was captured, and Zhu Di ordered him to be executed in Ling Chi.
