The date of moving has been decided. Can the newly bought sofa and bed be moved into the house in advance? Or live together?

This mainly depends on local customs. If you build your own house, you must let people live in the year when the house is built, or you can sleep for one night, even if you don't decorate it. Our custom there is not to move in at that time, so we have to wait three years to move in.

Also, if it is a newly bought commercial house or something, even if the date is set. Before moving in, you'd better ask someone who knows Feng Shui to take a look at it for you, and then burn incense to prepare Gong Mi (just like our family worships God). For the convenience of follow-up, it is best to bring a black dog in before moving in and let the dog go in to see if it barks. If the dog is okay, it's nothing, otherwise, you should pay attention. As the old saying goes, dogs can see things that people can't see.

Of course, if the landlord is a materialist atheist, then I don't have to read what I wrote above, and there is no problem moving in.
