A handy app for UK-based Chang Hon ('ITF style') Tae Kwon-Do practitioners, offering a general overview of training and knowledge.
Chang Hon (창헌) style Tae Kwon-Do is a traditional form of Korean martial arts developed by General Choi Hong Hi. The name "Chang Hon" means "blue cottage" and represents the style's emphasis on both physical technique and mental discipline. This overview respects the diverse groups and organisations that practice ITF-style Tae Kwon-Do across the UK.
ITF-style Tae Kwon-Do in the UK encompasses various groups and organisations, each with their own interpretations and practices while maintaining the core principles established by General Choi. The TKD4U app provides a general overview that acknowledges and respects these differences, serving as a reference for practitioners across different UK-based groups.
The Chang Hon system includes 24 patterns, from the basic Chon-Ji to the advanced Tong-Il, each teaching specific techniques and principles that build upon one another. While different groups may have variations in execution, the fundamental patterns and their meanings remain central to ITF-style practice.
