In this video, we learn how to change the strings on the erhu. First, loosen and remove the inner string. After this, take and unwind the new inner string. Then, take the end with the loop and put it through the Qianjing. Then, loop it in the screw at the bottom of the erhu. Then fold the tip of the other end of the string and put it through the hole in the first peg. Then, loop the string one and push the tip into the hole. Now turn the peg clockwise to tighten it. Repeat this for all the strings and you will have a finely tuned instrument.
