I'm from Shandong Peninsula, and my surname is Zheng. There is a saying in our country that we immigrated from Yunnan. Is there any origin?

I only know that Zheng He is from Yunnan.

Zheng's surname originates from Ji's surname, and its ancestor can be traced back to Hou Ji. Hou Ji is a legendary agricultural god. His mother is a descendant of Emperor Yan, and she is a princess. According to the records of the Five Emperors, Di Ku was the great-grandson of the Yellow Emperor. So the blood relationship between Yanhuang and Huangdi merged into Zheng surname. The 25th generation after Xia Ji is Ji You. When he lived in, he was Zheng's ancestor, namely.

During the Warring States period, Zheng was annexed by South Korea, and his son Lu led the crowd to flee. During the Chen and Song Dynasties (now around Huaiyang and Shangqiu in Henan Province), people took Gongzilu as their ally. In memory of their old country, they changed their surnames to Zheng.

First, Xingyang Zheng surnamed the world.

After the Han Dynasty destroyed Zheng, a civil city was built, located on the northwest bank of Yingze, hence the name Xingyang. Because Xingyang is the birthplace and prosperous place of the Zheng family, most of the Zheng family came from Xingyang later, so there has been a saying since ancient times that "the Zheng family came out of Xingyang and the Zheng family in Xingyang spread all over the world"
