Here's a breakdown:
* Min Nan Chinese (Hokkien): This is the dominant dialect in Xiamen and the surrounding region. It is part of the Min branch of the Chinese language family.
* Mandarin Chinese: While not as prevalent as Min Nan, Mandarin is the official language of China and is widely understood in Xiamen. It's used in government, education, and media.
* Other Dialects: There are other minor dialects spoken in Xiamen, but their usage is limited.
It's important to note that Min Nan Chinese has significant variation across different regions. The dialect spoken in Xiamen might not be fully understood in other parts of China, even by those speaking other Min dialects.
Overall, if you're planning to visit Xiamen, learning some basic Min Nan Chinese phrases would be helpful, but Mandarin will likely be sufficient for most communication needs.
