Put some forms and pens on the registration desk so that newcomers and guests can fill in the gift registration form.

4. Put some display cases and shelves in the scene, so that the newcomers can show the gifts they want and the guests can choose to buy them.

5. Put some gift wrapping materials and labels in the scene so that the guests can wrap the gifts and mark the names and addresses of the recipients.
