Chinese compound surname in the context of "Shangguan (surname)"

The Yuwen (Chinese: 宇文; pinyin: Yǔwén < Eastern Han Chinese: *wa-mun < Old Chinese *waʔ-mən) is a Chinese compound surname which originated from a pre-state clan of Xianbei ethnicity of Xiongnu origin during the era of Sixteen Kingdoms in China, until its destruction by Former Yan's prince Murong Huang in 345. Among the eastern Xianbei clans that ranged from the central part of the present day Liaoning province and eastward, Yuwen clan was the largest, and was awarded the position of the leader of eastern Xianbei (東部大人) by Chinese rulers. A descendant of the Yuwen tribe, Yuwen Tai, established the Northern Zhou dynasty in the 6th century.

Yuwen were descendants of the nomadic Xiongnu who assimilated into the Xianbei after 89 CE and ruled the Kumo Xi and Khitan (both Mongolic peoples) before being defeated by Murong Huang in 344, upon which Yuwen separated from the Kumo Xi and Khitan. The language of the Yuwen is thought to be Turkic or a very distant branch of Mongolic.

The Hundred Family Surnames (Chinese: 百家姓), commonly known as Bai Jia Xing, also translated as Hundreds of Chinese Surnames, is a classic Chinese text composed of common Chinese surnames. An unknown author compiled the book during the Song dynasty (960–1279). The book lists 504 surnames. Of these, 444 are single-character surnames and 60 are double-character surnames. About 800 names have been derived from the original ones.

In the dynasties following the Song, the 13th-century Three Character Classic, the Hundred Family Surnames, and the 6th-century Thousand Character Classic came to be known as San Bai Qian (Three, Hundred, Thousand), from the first character in their titles. They served as instructional books for children, becoming the almost universal introductory literary texts for students (almost exclusively boys) from elite backgrounds and even for a number of ordinary villagers. Each text was available in many versions, printed cheaply and available to all since they did not become superseded. When a student had memorized all three, he had a knowledge of roughly 2,000 characters. Since Chinese did not use an alphabet, this was an effective, though time-consuming, way of studying character-recognition before going on to understanding texts and writing characters.
