People who have spent time in other cultures often talk about "reverse (反向的) culture shock". If you leave your country for more than a short tourist trip and then go back home, you may feel it.
What is"reverse culture shock"? Well, imagine the following; You have just adapted (适应) to a new culture and have come to enjoy life in it. You have made new friends and have had a great variety (多种多样) of new experiences. Then, sadly enough, it's time to leave, but you are also very excited about going home. Arriving home is wonderful—seeing all the friends and relatives you haven't seen, eating all the special foods, reading the newspapers and hearing music you haven't heard in such a long time. But then after a few weeks, perhaps, things may not seem so "wonderful". You may become critical of your home country where you have grown up. You may not like certain things or ideas. In your eyes, either you or your home country has changed so much that you begin to worry.
So some experts explain it like this: When a person lives in a different cultural environment for a period of time, experiences cultural shock and adapts to the foreign culture, when he returns to his motherland, he appears symptoms (症状) of not adapting to his own culture. It's a difficult period, and many people experience it after the excitement of coming home has worn off. Luckily, it doesn't usually last as long as adjustment (调整) to a new culture does.
