Dear Uncle Dixer: My car is parked right in front of my front door. What should I do to have positive energy enter my home?
Answer: Try to avoid parking your car right in front of the front door because it would block the good Qi from coming into the house.
But if you cannot avoid it, then make sure your car is a source of pride to you. Keep it clean and tidy and well-maintained, so at least it is a welcoming thing to see when you park it at the front door.
