Born with remarkable drawing talents, he created numbers of drawings all his life, ranging from figure and landscape paintings, portraits, wooden prints and religious pictures, many of them being considered masterpieces.

Influenced by realism, he paved a way of drawing realistic pictures, bidding farewell to painting style employed by aristocrats at that time.

Based on diverse themes and unique drawing techniques, his paintings beautified working and enjoyable life of popular people, while ridiculing feudal bureaucrats for their corruption.

Typical of them are "Picture of Peasant's Life", "Picking Medicinal Herbs", "Wrestling", "Gambling of Aristocrats", "Kuryong Falls" and "Boat".

His drawings that marked a new milestone in Korea's picturing in that period are preserved as national treasures.
