Hi Ann.
Congratulations on your new hamster!
I have actually never laid eyes on a Chinese except for pictures as they are restricted in my state. I can't give you specific information, but I would wait and hopefully a member named cypher will answer questions for you. She is really knowledgeable and I know she has had chinese hamsters before.
As you said, hamsters can have their own personalities, and I was advised here to let my Syrian settle anywhere from 3-7 days. I've heard chinese are a shy species, but hopefully cypher can be of help. I'm sure there are others here as well who can probably give you advise.
Best of luck, and congratulations again!
