Yoon Heechul is a cultural-content creator whose YouTube channel Heechulism has already generated over 120 million views. Yoon earned over 100 million won in just six months by launching an English learning business when he was a junior in university. But the following year, his online sales agency flopped. With the 3.8 million won that he had remaining, he traveled the world at the age of 28. He created videos introducing cultures of the world and posted them on YouTube. In less than a month, he was able to secure a stable income, which he had dreamed of. Over the course of a year and a half, he traveled to 35 countries and produced over 250 videos. In the past two years, he has attracted an additional 370,000 subscribers and now his total viewership—over 500,000 people—gains various insights from his videos.
