Helping Feng Shui master in the countryside, the two brothers live in two courtyards. Is there a wall between the two yards?

Feng Shui pays attention to one house and one front door, which can be built according to two houses. Each has its own yard, and the key is that each has its own front door. (that is, the gate of your own fence), if you don't separate in the middle, you won't touch the courtyard wall. Turned into a crying door. There are two ways to solve this problem, or we should just open a main gate on the fence between two houses and use one gate. Or meet the middle courtyard wall. Enter every house. There is no door left in the middle.
