Hundreds of Surnames is a book about the surnames of China, which was written in the early years of the Northern Song Dynasty. The original surname was 4 1 1, which was later supplemented to 504, including 444 single surnames and 60 compound surnames. The order of hundreds of surnames is not the actual arrangement of surnames, but because they are easy to read, learn and remember. Hundreds of surnames, together with San and Qian, are also called "three thousand", which is an enlightenment book for children in ancient China.
