Migration and Distribution (Lack of information) The SITU family name is not ranked among the top 100 in the Hundred Family Surnames on the Chinese mainland and in Taiwan. The SITU family name originated in the pre-Qin period. In all dynasties, there was a position called "Situ", which was responsible for the country's administrative affairs. Some descendants of the incumbents of the Situ position took the official title as their surname and were called the SITU clan. Similar to surnames such as Sikong and Sima, Situ initially specifically referred to an official title. As early as the Shang and Zhou dynasties, there was a position called Situ, which was in charge of the people, land, education, and administrative affairs. In the Zhou Dynasty, it was called the Grand Situ of the Ministry of Earth, and its position was similar to that of the prime minister. Many states in the Spring and Autumn period continued to have this position. It is said that Shun served as Yao's Situ, and his descendants took the official title Situ as their surname. In the State of Wei, Xia Chao, the son of the official Xia Wu, held the position of Situ, and later some of his descendants also claimed the SITU surname.
