Okay, let me help you come up with two transliterated English names.
For Chu Han, I suggest the name "Trinity". The pronunciation of this English name and the Chinese name are very similar. They both contain the sound of "tr", which also means that Chu Han has the stability of a triangle. sex and balance, and a multicultural background.
For Xinyao, I suggest the name "Shirley". The pronunciation of this English name and the Chinese name are also very similar, both have the sound of "sh", and it also means that Xinyao has a snow-white soul. and pure quality.
I hope these two names will satisfy you!
