Why is Zhu Yuanzhang three words and Judy two words?

Judy's name is only two words, which is entirely Zhu Yuanzhang's wish.

According to the Ming Taizu, Zhu Yuanzhang officially named the seven sons who had been born at that time on December 25th, the 27th year of Zheng Zheng (1367), and wrote in his message to the ancestral hall that the birth of a son was named after his father. Rituals are very important in both ancient and modern times. Since the bootstrap soldiers, seven children have been born across the river. Today, the eldest son is named Yue Biao, and the second is Yue Yong, Yue Tong, Yue Di, Yue Zhen and Yue Mi. I dared to tell Sun Yi (later renamed Shou Qian).

In addition, it is an unwritten tradition that ancient emperors were famous for nothing.
