To prevent playing the guqin, you need to change the position of the fingernails and press the strings. Do not grind the fine meat under the nails. Also pay attention not to grind blisters. It is best to stop immediately when the blisters are about to bubble. Put a thin layer of adhesive tape on the part where you press the strings, remove it when you are not practicing, and stick it again when you are practicing.

People with fragile fingernails can improve it by eating a calcium-rich diet, sun exposure and other methods, and pay attention to supplementing the body with calcium, and the nails will gradually thicken.

When your fingers no longer hurt, you don't need to stick them again. Repeat this until the cocoon is ground and the pain is no longer there.

Playing the guqin requires that the nails and fingertips have half the flesh, and the outer side of the thumb of the left hand and the left side of the ring finger should also be half the flesh when pressing the strings.

"Yuguzhai Qinpu" records the maintenance method of nails. Prepare equal parts of ginger and Baiji, slice them, boil them in water to make them thick, dip them on the nails, and they will become hard and strong for a long time.

The specific method is to put Bletilla striata into a bowl and immerse it in water. When the water becomes viscous, cut the same amount of ginger slices, add one liter of water and boil it twice. Dip each finger in it for 1 minute, and it will be absorbed more completely after it dries naturally.
