The Kicho hyeong were developed as a basic, simple form for beginners. The symbol used in Tang Soo Do for the Kicho hyeong is a human baby learning to walk. The pattern is also visible in the increasingly complex forms that follow. Hwang Kee used these forms to teach applications of basic moves and techniques. These forms are also influenced by the Wa Ka Ryu style of southern China. These and the Pyung Ahn forms to follow are characterized by speed, aggressiveness, dynamic action, and quick reaction.
