Can I cook in the new house before I officially move?

Can I cook in a new house without a formal move? Cooking can be done in the new house as long as there is water, electricity and ventilation. . .

Because the new house has not been moved to cook, and there is no Feng Shui theory, the house can cook, and it is no problem to move or not.

Moreover, China is so big that families move every day, so there are no special taboos.
