Wearing suitable guzheng nails is also called "prosthetic armor", which is very important for guzheng hobbyists and players. It directly affects the feel and timbre of the strings. Especially for beginners, these precautions for wearing prosthetic armor must be paid attention to.

1. The width of the tape is preferably 0.9cm
2. When the tape is wrapped, try to expose as little as possible the root of the prosthesis, and expose as much of the distal end as possible
3. The tape is placed on the back of the finger, half the nail and half the flesh
4. The length is preferably wrapped in two and two-and-a-half circles, and ends on the back of the finger or the belly of the finger
5. The overlapping of the tape should be neat and not staggered
6. The direction of wrapping the tape: clockwise from the far side of the right hand; counterclockwise from the far side of the left hand
7. The texture of the adhesive tape is cotton, and it is often changed
8. Roughly the tip of the prosthesis is radially, and the angle is 45 degrees radially
9. The midline of the big finger prosthesis is a little bit to the ulnar side of the midline of the big finger, so it should not be too straight
10. The midline of the prosthetic nails of the two, three and four fingers should be aligned with the midline of the fingers
11. The proximal end of the prosthetic nail should be far from the knuckles, and should not touch the knuckles, or even exceed them.
12. The exposed length of the left hand armor should be slightly shorter than the right hand.
13. Buying fake armor: the playing surface of the fake armor is curved
14. The left armour is slightly thicker than the right armour
