"Long time no see" is a very interesting sentence. When I first read this sentence from an American friend's email, I laughed. I thought it was a perfect example of Chinglish. Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too thrilled to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing "Long time no see." This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily.

Soon after Charlie Chan, "Long time no see" became a popular phrase in the real world with thanks to the popularity of these movies. Some scholars refer to America as a huge pot of stew.

American Chinese, though a minority ethnic  group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew. You can have some other examples than adoptions from Chinese, such as pizza from Italian, susi from Japanese, and deja vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant, or to buy a bottle of iced Chinese green tea with honey in a grocery store. Since Americans appreciate Chinese culture more and more nowadays, I believe more Chinese words will become American English in the future. In this way the American stew keeps adding richness and flavor. The main idea of the passage is that   _  .
