How to pronounce “samchung” in English

I have studied astronomy and published books. Recently, a group of 60-70 science journalists and novelists opened a science book cafe.It opens on May 1st at Samchung-dong. We are centered on science and talk about cultures. I know science is not a friendly topic but we see science as a culture so we gather up and discuss.My generation gained knowledge by reading books and that is why we opened a book cafe.
