어찌 손끝에서 소리가 울리지 않는가?

After interacting with the spirit in the Gujin, you'll receive a Gujin Recording which you can bring over to Gongyu who is found in the Exalting Sanctum. After giving her the recording, she will present you with a New Gujin Recording which you can bring back to the spirit.

A quote from the poem 題沈君琴 (Commentary on Sir Sheng's Guqin) by Song dynasty poet Su Shi: "If there is sound on the guqin; Why doesn't it play when put in the box? If there is sound on the fingertip; Why can't I hear anything from your fingers?" - Credit: Necrosyrtes
