Zhu Guochen (CHEN), Xuan (XUAN)
Both are OK. Chen and Xuan are both characters for ancient emperors, and the key is that your friend leaves around 6:50 in the morning
Sheng, Chen and Xuan both mean the rising sun, very energetic and lively!
Coupled with the first two words "Zhu Guo", it is prosperous and full of vitality.
It is also not vulgar, and generally does not have the same name as others.
Hope you like it! !
