Our company is a Korean language academy that has trained over 4,500 students over the past 16 years. Our clients include children of parents in politics and business, including former President Lee Myung-bak. Building on this expertise, we have launched <Ddong Hangul>, a Korean language textbook for children of Koreans living abroad. <Ddong Hangul> has been copyrighted in the US and has been exported to New York, with plans to export nationwide soon. This Korean language textbook, <Ddong Hangul>, is a unique storytelling textbook based on the concept of poop. It follows the adventures of four poop characters as they master the Korean alphabet. It is designed to enable children ages 5-9 and adults to learn Korean easily and enjoyably with the poop characters. With the increasing number of Korean language learners in the US and around the world, and growing interest in K-culture, we hope <Ddong Hangul> will be a helpful tool for Korean language learning.
