Why is the son of Zhu Yuanzhang's eldest son named Zhu Yunwen, who is born in the Yun generation, while the son of his fourth son Zhu Di is named Zhu Gaochi, who is born in the Gao generation?

Hello, host! Zhu Yuanzhang revised the Zhu family genealogy and revised 20 characters for all the descendants of his sons. Zhu Yuanzhang's sons are all named with the character "木" (for example: Prince Zhu Biao, King Zhu Di, King Zhu Di, King Zhou, etc.) and his grandchildren and descendants are given different names to avoid duplication of names. Of course, this can also make it easier for modern people to use this. The information came to the descendants of the Zhu family. Therefore, Zhu Biao's son was named Zhu Yunzhen according to the 20 characters given by Zhu Yuanzhang, which started with "Yun", and Zhu Di's son was named "Gao".
