For example, the country name is "Yan" (because it favors Huode). The year name can be changed according to the history. Jianming, Kaiming, Zhongxing, Yongxing... and the princes of this country can use all of them. Names next to the character for fire (single characters, in ancient times, single names were usually honored, while double-character names were generally of low origin), such as Shuo, Huang, Deng (囧, I made this character as a joke ^_^) and so on~! ~~
