Xi "is considered as a complete surname. There is this surname "Xitala" in Manchu, but now the surnames of China people are basically changed to Zu, Tu and Tu. However, there are no full surnames in the hundred surnames. Hundred Surnames was written in the Song Dynasty, with 442 single surnames and 6 1 compound surnames, with a total of 503 surnames. I have seen hundreds of surnames, but I have never seen the name Xi.
