How They Do It In Dubai

	My first impression of this country is that it is a city in the middle of desert. I arrived Dubai at night, as such, I could not view the city from the airplane. I could only see that there are lights every where in the city. In the morning, I found this country does not seem to be in the desert, because I can see greenth everywhere.
	Few days later, until I see this, then only I know how they turn desert into greenth. If you go to the desert, you will not be able to see this kind of flower, because in the desert, it seldom rain. According to some local people, it rains once or twice in a year only. This kind of flower needs water.
	How they do it? First, the worker will lay the black color pipes on the ground, then over lay the grass with soil on top. Every morning, the worker will feed water into the pipe. With water, the grass can growth, and finally it covers the surface of the desert.
