In this regard, Yun Thae Gun, chief engineer of the factory, told KCNA:

The factory has renewed the design of external shapes of accordion and bayan, improved the sound quality by increasing the wind pressure and enhanced the accuracy of pitch.

Its products took the first place at domestic shows and exhibitions for several times. And they won a high appreciation at an international musical instrument exhibition held in China in October last year.

The factory produces 50 kinds of accordions and 20 kinds of bayans at present.
