Most of the Miao four-string performances are performed in a sitting position. The piano box is placed at the root of the right thigh in front of the right abdomen.

The index finger, middle finger, ring finger and little finger are used to press the strings; the right elbow and right wrist hold the piano case, and the right thumb and index finger (or middle finger) hold a bone-made plectrum to pluck the strings at the round hole above the bridge to make sounds.

The tuning of the four strings of the Miao ethnic group is divided into two groups, the first and second strings are one group, and the third and fourth strings are another group. The sound is round and soft.

The four strings of the Miao ethnic group can be played in various ways, and can be used for solo, ensemble or as accompaniment to singing and dancing. Young men and women of the Miao nationality often play and entertain themselves in slack farming or work, and often play in ensemble with Miao nationality sanxian and other musical instruments.
