The creation and development of the Korean-style alphabetic choreography is associated with the immortal guidance of Chairman Kim Jong Il and the respected General Secretary Kim Jong Un.

The Chairman gave invaluable instructions to further develop the Juche-oriented and popular alphabetic choreography in his classic works such as "On Completing Juche-Oriented Dance Notation" and "Theory of Dancing Art".

The General Secretary learned about the successes made in the research for putting the choreography on a scientific and IT basis on several occasions, and clearly indicated the orientation and ways for its completion.

Officials and researchers of the bureau optimized the choreographic alphabets and the mode of their combination and further improved the scientific accuracy and simplicity of the alphabetic choreography by pooling their creative wisdom and passion, thus developing the perfect choreographic helper "Ryuldong".

The dance creation support system "Ryuldong" consists of the dance script editing program "Paekhak", dance simulation program "Mujigae", choreographic alphabet input program "Hanadul" and dance notation learning program "Phyogihakgyo".
