Xiang surname, the original surname is compound surname: Sima. Cause: Zhuge Liang refused to return the land (now western Hunan) and hoarded troops to drive away the local Tujia people. His company commander's surname is Sima, and Zhuge Liang gave him the surname Xiang (Xiang: meaning the window of Asahi) and lived permanently. The leader gave birth to nine sons, who became the current nine surnames. There are four existing folk houses in western Hunan, and Chongqing in Sichuan is one of them now. Other branches rarely exist and cannot be verified. (Because after Zhuge Liang, no historian has made a real textual research on surnames, and they all follow the previous history books, so the real origin of surnames has not appeared in the current history books. )

Historical records show that Xiang's surname is related to Guo Xiang, Shandong Province, and that "Yan Di Shennong was followed by Xiang's surname and Jiang's surname" is true, but this family has long been cut off.

Therefore, the origin of the existing Xiang surname is not the Xiang surname mentioned in the history books.
