Why are Huang Yancheng and Huang Yueying in The Romance of the Three Kingdoms all three-word names?

That's a good question, because in the Three Kingdoms period, the names of both words were base names, and Huang (not Huang Yancheng) was born in everyone, so naturally he wouldn't take the base name. Huang's name is mainly found in Biography of the Three Kingdoms and Zhuge Liang, and Pei cited Xiangyang Ji and Xiangyang Ji Jiu Ji, which is probably a word, not a name. Huang Yueying, ancient women had no names.
