Recommended name: Guo Jiaji Guo Jiayin Guo Jiagen Guo Jiajun Guo Guo Guo Jialiang Guo Jiali Guo Jialing
I think the best ones are: Guo Jiagen, Guo Tongjia, Guo Jialing, Guo Jiali and Guo Jialiang (the five elements of Mumuhuo), and the eight characters like fire best.
I hope there is a name you like in it.
