Abu Dhabi, the capital of the United Arab Emirates, is itself built on an artificial island with a landmark object, a flagpole more than 200 meters high, which is also known as the world's tallest flagpole. It is reported that the flagpole is more than 200 meters high, and the flag on it is 40 meters long and 20 meters wide. The total area of the flagpole is 800 square meters, which is equivalent to a small half of the football field. Although it doesn't look very big, it's because it's too high. You can't think it's small if you compare it with the building below. Just below the flagpole is the Museum of Abu Dhabi, also known as the Folk Village. The buildings and environments inside reproduce the living conditions and features of the aborigines here at that time. In folk villages, there are also many animals, including sheep, cattle, chickens and ducks, and other livestock and poultry. There are horses, camels and mules in another place. Among them, the mule is the most interesting one. When someone comes to visit it, people usually go to the camel with the most desert characteristics first. But the old man is jealous, and beside it, he makes a loud "ah-ho" call to attract people's attention. There is also a well in the courtyard. Abu Dhabi is an emirate with high precipitation, especially in the Alain region of Abu Dhabi. This well in the folk village shows that the ancient Abu Dhabi people also got fresh water from groundwater to survive.
