1, Zhu Chenjun and Zhu Houzhao are brothers. Zhu Chenhao is a character in the TV series Tiger in the Wulin. He is the son of Hui Wang, and he was succeeded by Hui Wang. According to the plot in the TV series, Zhu Chenhao is the son of Ming Hui Wang Zhu. However, in the real history, Zhu Changrun was the Ming Dynasty's Minghui king, and there was no Minghui king Zhu. Therefore, Ming Hui Wang Zhu belongs to a fictional character.

2. Because Zhu Yuanzhang gave each son a generational table with 20 words each, his grandchildren began to name them according to their age. Among them, 20 words in the home backup table are: "Look forward to seeing you, be generous and easy, pay equal attention to kindness and grace, and take care of Emperor Jianjing first."

According to the generational table, the fictional Zhu and Ming Xiaozong belong to the same generation, and Ming Xiaozong's son is Ming Wuzong.

4. Therefore, as the son of Zhu, Zhu Chenhao and Mingwuzong are cousins.
