All Korean text books teach students how to speak standard Korean, which is the dialect found in Seoul. However, Korea is a mountainous country that until very recently was difficult to travel around. As a result, each region has strong regional dialects, called ‘satoori’ in Korean. The best way to learn satoori is from a native of that province as satoori is generally spoken rather than written. This can make it hard to learn from written sources as it will be written phonetically whilst regular Korean (despite what many people think) is not written perfectly phonetically. This makes it more difficult to make the connections between sounds in satoori and regular Korean through reading alone.
