Extended data:

As we all know, there were two-character compound surnames in ancient times, such as Nalan Xingde, Dong Fangshuo, Sima Qian, Sima Xiangru, Sima Guang and Zhuge Liang, all of whom used compound surnames.

Wang Shizhen, a famous historian in the Ming Dynasty, found that the number of compound surnames had become less and less. He believes that the reason why people have fewer and fewer compound surnames over time is for convenience, so people simplify the complex and take gongsun, wangsun, etc., which are commonly used in Qin dynasty, and then change their surnames to "Sun", Gongsha, Ram, Gongcheng, etc., and then change their surnames to "Gong".
