Qin emblem plays the role of marking the phonemes - it is the marker of the position of the strings and the node of the overtones when playing the fretted notes. It is generally made of jade, gold, mother-of-pearl, etc. and is inlaid on the surface of the piano. Guqin has thirteen emblem positions, from Yueshan to Longqin (from the beginning of the qin to the end of the qin), the first emblem, the second emblem... and the thirteenth emblem at the end of the qin.

The emergence of qin emblem promoted the establishment of the guqin form, which made the development of guqin music more perfect and played a vital role in the development of rhythm studies. As for when the guqin emblem was produced, there is no accurate historical record so far.
