Can I share a room in the new house before moving?

From the perspective of geomantic omen, if there is no occupancy ceremony for the new house, it is best not to move in, because the atmosphere of the new house has not stabilized at this time, and it is unfriendly to the new house or to oneself to move in rashly, and the new house is usually held on the day of occupancy.

The day of moving generally refers to the auspicious day of holding the "ceremony of entering the house".

Open doors, burn incense to worship ancestors, make a fire or set off firecrackers. They are all symbols of a formal move, so without these ceremonies, it is not a real move, just a move, so don't move into a new house until you move.

The above is from the perspective of traditional feng shui theory. Whether to hold the check-in ceremony depends on your own wishes and local customs.

However, whether there is a check-in ceremony or not, on the first day of moving into a new house, it is best to boil some water or light a lantern. If you can't turn on the lights all night, it's best to turn on the lights for a while. One is to ensure the luck of the new house, and the other is to pray for evil spirits, which will help improve the future fortune of the owner.
