According to the general custom, on the first day you move into a new house, you should make a fire and cook.

Moving is moving from an old house to a new one. Since it is a new house, it is necessary to fire, which means that life will be rich in the future.

If you don't want to cook with fire, you can boil a pot of boiling water. This is what Guangdong means when it calls moving to a new house "joining", but this is a folk custom, not stipulated by anyone. Cooking with electricity is also a partnership, and it should be regarded as a partnership. In fact, these things are all a form. You feel like you're living in a new house and you're officially cooking. Cooking with any fire is a partnership!
