What does the word "di" in the surname mean to read?

In the surname, Di is pronounced dǐ. The surname of Zhonghuafu is a descendant of Emperor Jiuyu, one of the four kingdoms of Guishuang Empire. On the one hand, Guishuang Empire was established by Daxia people, on the other hand, it was established by Dayue people. But as far as bloodline is concerned, the two are almost the same, and they are both Tuholo people. The disappeared Loulan people are also Tuholos, Uighurs are half Tuholos and half Turks. There is a small place in the south with a place name as its surname, which has nothing to do with the Tuholo people.

Extended data:

Di's family name originated from the Hui nationality and belongs to the surname changed from the name of the ancestor of China. Di among the Hui people originated from the great immigration policy implemented in Yongle period of Ming Dynasty. The Ming government forcibly moved some Hui people living in Yangzhai, Henan Province to Taiyuan, Shanxi Province. This part of the Hui people is called "Jindi" because they are nicknamed Taiyuan, Shanxi Province and Yangzhai in ancient times, and their original place of residence is also called "Diyi". So according to the custom of China people, it was changed to Han surname, called Di, which was passed down from generation to generation and became one of the top ten surnames in Taiyuan today.
