First, in front of this shed, around the open space in front of the house, you can see other mountains or buildings in the distance, just like a flat land is surrounded. This is called the lock of the Tang Dynasty, which is a good thing, but after adding the melon shed, it is tantamount to narrowing Tang Ming, that is, narrowing the income path. This is evil.
On the other hand, if there is no open space in front of the house in front of the melon shed, there will be nothing around. If it is scattered, the money can't be gathered, which is called failure to pay back the money. At this time, the participation of the melon shed can make money gather in front of the house. Although it's a little small, it's better to have a little money in than a lot of money out.
