The prince of Qatar wore a piece of cloth because of local customs. According to relevant data, the ancestors of Arabs and the earliest settlers in the Middle East involuntarily chose robes and headscarves as their distinctive clothing in order to adapt to the arid, rainy, windy and dusty living environment and the obvious temperature difference between day and night. The headscarf can not only protect against the sun, but also keep out the cold. When the dust is flying, it is a sharp weapon against wind, and it is also an essential carry-on thing.
