Do some research about the culture of your target language and write about the 'linguistic aspects', e.g., body language, how people talk about time, etc.
Since I am an exchange student from Taiwan, I think Korea and Taiwan have a lot of similarities when speaking of cultures. Different from Americans, Koreans don't like that much of eye contacts and skin touch. For example, when meeting a friend on the street, in America people like to hug when say hi; however, in Korea or in Asia as a whole picture, people don't hug because most of the time we feel awkward when hugging someone except for the families or lover. Also, body language is less than American's as well. Instead of using body language like doing some gestures while speaking to emphasize something important, Koreans prefer to use different tones while speaking.
My interest in Korean language and culture come from Korean dramas and k-pop. Since I began to watch Korean dramas, I fell in love with its culture. Although Korean culture is quite similar with Taiwan's culture, but there are still some interesting differences like the way people interact with each other and different food style, etc. Thus, I want to know more about Korean culture and its language.
During this semester and this year, since I already have some basic Korean language knowledge, I would like to learn how to speak in Korean fluently and know how to chat with Korean friends. In the future, I hope I can speak Korean like the natives and also be able to use this skill during traveling or doing some Korean related business.
