Most hams don't much like us picking up their houses or taking the roof off tbh, understandable really! It's totally normal for Chineseys to burrow down in the substrate rather than just sleep on top of it or in a little nest inside the house, I find with mine if they can't get out of the house underneath they will just chew their way out!
If you can it's probably best to just interact with them or check on them when they're out & about in the cage unless you hear noises that could indicate a problem coming from inside the house.
