Now, I am going to explain why such a mysterious phenomenon is happening on this road. There is a scientific explanation behind it, even though I personally find it hard to believe. I am placing a carpenter's level on the road, and incredibly it shows that this road is NOT going downhill. But when you see it with your naked eye, you can swear that it is going downhill. Somehow, the carpenter's level clearly shows that the road is going downhill towards the opposite direction, which explains why the cars and balls rolled back from the stop sign. This is known as a "Gravity Hill" Phenomenon. The road seems to be playing a clever trick with my eyes and even with my camera, it seems impossible to believe that the road is going down on the opposite direction.
