What materials should residents prepare before they want to move in?

By check-in, you should mean delivery.

First of all, we should arrange the delivery place, shopping guide card and bathroom instructions.

On-site reception, fruit, candy. You don't know what water is.

Then there are forms: house acceptance form, maintenance and rectification form, owner basic information registration form, preliminary property service agreement, temporary management agreement, and possibly decoration agreement. Owner's manual, key application registration form, fire safety management agreement and some documents to be signed. Some people may want to decorate immediately, so they need to prepare the decoration application form, the construction personnel registration form, the open flame application form, the anti-leakage commitment letter, the decoration permit, the temporary pass and so on. A lot.
