When my wife and I went to live in an Arab country, my friends told us to
be prepared for a culture shock (文化差异). Later, we realized that the advice
given to us by our friends was correct.
The culture shock started with the weather. Here, the burning sun can cook
an egg in a minute! The hot weather made us feel so tired that we were falling
asleep at midday!
Another culture shock was the working week. We worked from Saturdays to
Wednesdays, including Sundays. It was also strange to see people praying
(祷告)in a certain direction! They have strict rules for women. They do not let
people see their faces in public. 'I'hey do not let women drive cars, either. All
dresses worn by women have to cover the bodies completely. They believe that
women cannot be seen in public.
At the weekends, we went camping in the desert. I will never for-get
watching the sun setting over the desert. We also enjoyed riding on the camels.
In the end, we enjoyed living there, but their culture is very different from the
American culture.
