Byeon is famous for his precise depictions of animals and people in detailed brushwork.
He served as a royal painter of Dohwaseo, the office of painting and then as a hyeongam, a magistrate of a small province.
Myojakdo housed in the National Museum of Korea captures a lively scene of two cats and alarmed sparrows around a tree in detailed brushwork.
The depiction of a group of chirping sparrows on twigs are illustrated precisely with very detailed brushstrokes.
It is based on his deep affections toward animals and close observations in real life.
