Pulpis literally mean playing a flute with grass. The Chinese character is also called Chokjeokkeum, which is played by folding leaves or grass leaves and whistling them on the lips. It is said that peaches and citron leaves are used a lot.

The record of the grass flute is the oldest recorded reed or reed flute in "Suseo" and "Dongdongjeon-dong" and also features a portrait performance in the poem "Someone picks a green leaf from a forest, blows it in his mouth, and makes a clear sound" in the poem "Moon Ga-seong" by Lee Gyu-bo during the Goryeo Dynasty. In 1493, "Akhakwebeom School" compiled by Seonghyeon and others during the reign of King Seongjong of the Joseon Dynasty recorded the types, materials, and methods of performing the full flute in detail. In "The Annals of the Joseon Dynasty," there are several records showing that the court had a musician playing the initials. In addition, a collection of calligraphic works by various writers showed that they enjoyed playing them from the top to the king to the commoners below. And Kang Choon-seop, a first-time music expert on meteoric albums, has recorded music such as "Hwimori" and "Gutgeori" with the same music as Sanjo. As such, the Pulpieri has been one of the musical instruments enjoyed by the Korean people throughout its long history, and has been recognized not only by the private sector but also by the official instrument.

"The Evil Trapezius" records that anyone can play the instrument so easily that it is not difficult to make a sound and play it by saying, "You don't need the teachings of your ancestors, and you can only know all the syllables first." In fact, the full flute is easy for anyone to learn and play, and any music can be freely played. Today's first play is a folk song, a Cheongseong song, a Sanjo song, and other traditional pieces of music.

In Gyeonggi-do, Oh Se-cheol was designated as the holder of a full flute, and he continues to perform actively.
