First off, Chinese hamsters are MOSTLY a look no touchy pet
My girl Bella prefers not to be handled which is fine by me! Instead I just stroke her and give her treats it's still super fun!
You can try luring her out of her house with treats, not too sugary as chinese' are diabetic prone! See if she takes it off you...if not...wind back a few steps! Sit by the cage and talk see if she comes out at all! Keep trying this until she's confidently taking treats etc!
REMEMBER take it at her pace and don't rush! Patience will be your best friend!
If this doesn't work and you've tried repetitively you may need to accept the fact Snibbs wants to be a looky hamster, don't worry this can still be fun!
