“I stay in a house where the road outside is higher that the house, Each morning, I have to drive my car up the slope to reach to the main road”
In normal circumstances, it is not very good to stay in a house that is lower that the main road or has the outside main road on higher ground.
Living in such a house is considered bad in FengShui. The main road is like a dirt and waste gas pipeline ending at your house when moving vehicles constantly mowing along it. Pollutants from these cars and lorries will be very harmful to your family health.
The chances of having accidents are much higher and this can happen anytime and unpredictable.
There is a cutting Qi which rush and cut into your house like a knife and this will bring mishaps and quarrels.
The chances of having peeping toms are much higher. This also indicate that you will meet with more petty person that are always out there trying to harm you.
The others problems include flood and landslide
