Yun's family came from Xiaguan during the Yellow Emperor's period and was named after the official position. According to the history book "Shi Yuan", "Jinyun's Empress." According to the historical record "A Textual Research on Surnames", Jinyun, the ancestor of Yun, was a native of the Yellow Emperor and took the official as his surname before Zhu Rong. Jinyun is the official name of the Yellow Emperor era. The Yellow Emperor took the cloud as the official name and managed the affairs of the four seasons respectively.

Among them, the official name of Xiaguan is Jinyun. The name of Jinyun, who was in charge of summer affairs at that time, needs further research, but his descendants took the word "Jinyun" as their surname, which was later handed down, and then shortened the word "Jinyun" to marble, simplifying it to marble today.

Yun's ancestors:

Zhuan Xu, the ancestor of Yun, is the grandson of Huangdi, the ancestor of the Chinese nation. He once ruled the world for 78 years. His descendants have a wide range of reproduction and are the most important members of the Chinese nation. One of his descendants used to take Da as his surname, and Yun was separated from Da. Visible, cloud is the offspring of Zhuan Xu.

Since the surname Yun comes from the most popular surname after Zhuan Xu, how can it be associated with "fire"? It is not difficult to see the answer to this question at a glance as long as you look at the records of the origin of the most popular name in Shuowen.

According to Shuowen, "the most popular name is after Zhu Rong." Everyone knows that "Zhu Rong" is synonymous with "fire". The origin of Yun surname can be traced back to more than 4,000 years ago, and having such an outstanding ancestor "Zhu Rong" who made contributions to the nation is not the most proud of Yun surname. Therefore, the descendants of Yun regarded Zhu Rong as the ancestor of Yun.
