The left hand of the guqin also uses only the four fingers of the middle name of the big food, and the little finger is still forbidden. The left fingerings are extremely rich, and can be divided into five categories according to their functions and effects: the main fingerings of the left hand, which indicate which finger to use and what technique to use to press the strings, including big, food, middle, name, kneeling, scattered, pan, etc.; There are also moving fingerings such as up and down advancing and retreating; there are strumming, dwindling, donating, bringing up, putting and closing, and other fingerings for strumming with strings; there are also decorative fingerings such as Yin, Xiao, Chuo, and Zhu; and compound fingerings for left and right hands. It is described as follows:

• Big (big finger): The distal end of the big finger is slightly bent, lying sideways under the index finger, the tiger's mouth is half-open, and the side is pressed on the string. There are two parts for the big finger to press the strings, one is the half armour and half flesh, and the other is the joints. When the two strings are played in a row, both parts are used. When pressing the strings, the second finger of the eclipse is slightly bent, the index finger is slightly bent, the forbidden finger is slightly warped, and the tip of the nail is slightly raised.
• 亻 (index finger): The index finger is naturally flat on the string, and is pressed with the skip. The index finger is mostly used for overtones. In addition, it is sometimes used together with the big finger. The big finger uses the half armour to press the inner string, and the index finger uses the left side of the skip to press the outer string.
• Middle (middle finger): Bend its root section, straighten its distal section, and press it on the string with the skip to the left. The two fingers of the food name are stretched flat, the big finger is on the side, and the forbidden finger is as before.
• Xi (name finger): Bend the middle section, make sure the distal section is protruding, press it on the left side of the skip, and four fingers are forbidden in the food. The middle finger should never be pressed against the index finger to help.
• (Kneeling finger): The index finger is bent at the middle section, kneeling at the distal section, and kneeling on the back of the finger to press the strings. There are two ways to press, or use the back of the nail, or use the joints, and use the left side to press. Kneeling fingers are mostly used for mid to upper pitch.
• 艹 (scattering sound): Use the right hand to play the empty string, and the left hand does not press, and the middle finger can be used to imitately point on the ten emblems.
• (Overtone): Play the string with the right hand, and tap the string with the left hand at the emblem position, and the sound is very clear. There are two methods: one is that the left finger is very close to the string, and the string jumps when playing, and the touch finger forms an overtone, which is called "pink butterfly floating flower". When playing a piece, the left finger is lightly tapped, and it starts at one point, which also becomes an overtone, which is referred to as "a dragonfly touches the water". When playing overtones, the right hand must be close to Yueshan, so that the sound is clear. For scattered overtones, only overtone symbols are used on the notation.
• (Rising): At the beginning and end of a qin piece, overtones are often used, and sometimes one or two ten-days or a segment of overtones are often inserted in the middle of scattered or percussive tunes. At this time, the "JA'" symbol is used to indicate that the following notation should be played as overtones.
• (Overtone): Used where a paragraph or a sentence or two ends with an overtone.
• Up: After pressing and playing, the left finger presses the string from the standard position to Yueshan and the sound is heard, and the right hand does not play again. Two consecutive tops are two tops.
• Down: After pressing and playing, the left finger presses the string from the original position to the next position, and the right hand does not play again. The second in a row is the second.
• (Jin Fu): After pressing the sound, one moves up from the standard and gets a sound to enter, and then returns to the standard to call Fu. Even the original bomb has a total of three sounds, one true and two false. Entering the complex twice is called double-entry complex.
• (Retire): After pressing the sound, the next person from the standard position is called to retreat, and the player still returns to the standard position to call back. If you return twice, it is called double return.
• (Separate): First click on the position with one click, then step up to the first position, and then return to the original position and play again. Two true and one false, a total of three sounds. The front and back are divided twice, and the middle is stepped once, so it is called separation.
• (Fold up): After the big finger presses the upper position to make a sound, the name finger is connected to the lower position, and at the same time, the big finger will play the string to make a sound. The method of folding is to use the edge of the big nail to push the string up and inward, and the ring finger is still pressed firmly.
• (Claw up), after the big finger is pressed, the tip of the nail will raise the string claw, and a scattered sound is obtained, which is called claw up.
• (Take up): After the index finger is pressed, the fingertips pick up the string, and a scattered sound is obtained, which is called taking up.
• (Playing and closing): After pressing the first finger, the string is released to make a scattered sound, and at the same time, the second string is pressed urgently and played to the right, which is in harmony with the released sound.
• (Synonymous): Also known as banding, the method of playing is to bring up the string after pressing the index finger, and at the same time play the other string with the right finger, the scattered sound is like a sound.
• (Yinghe): After pressing, the left finger is up or down, and there is a sound when walking, and the sound of the right hand playing the parting string is called Yinghe.
• Clumsy (pulling out): After pressing the middle finger, push the string outward to get a scattered sound, which is heavier than the band, and is dedicated to the first string.
• (绨): After the ring finger is pressed, the ring finger will be heard when the ring finger hits the string on the previous phoneme. Do not hit the piano surface.
• (Xuzhu): If you don't press and don't play, use your big or name finger to strum on the desired chord and position to make a sound called Xuzhu. (dotted dot) Same.
• (Virtual pressing): After the sound is obtained when playing, and the sound does not stop, use your finger to float on the string to suppress the residual sound.
• (Yin): After the finger presses and makes a sound, it oscillates left and right with the vibration of the elbow and arm.
• 犭 (猱): After the finger is clicked, it swings left and right with the wrist. Such as things have the power to stretch, with the expansion and contraction, continuous and continuous. The turbulence is relatively large, about two or three minutes, two or three turns back and forth, the sound is expensive and vigorous, and the finger movement is purely wrist force.
• BU (Chuo): Upper portamento. From the position down a little, the slant is pressed up in place, and it pops out loudly.
• 氵 (note): gliding sound. From the position up a little, the slant is pressed down to the position, and the bet pops up by this.
• Standing (collision): The button has been clicked, hit it a little with the finger, and quickly return to the original position with another sound. Generally, one sound is divided into two sounds, and there are also a few such as rushing forward.
• (Calling): Most of the qin scores believe that when playing on the right side, the chorus is doubled, the sound is lower than the standard by two points, and the speed is on the standard. like an echo. Only "Introduction to Qin Studies" explains it as "going up by taking the lower note, and then picking up the upper note and going down quickly, like a backlash and rushing back." It is also like an inverse echo.
• Dou (Double): When the rush is slightly out of position, it is called Dou with the sound of playing it quickly. Finger-moving is similar to bumping, except that bumping is used after playing, and it is separated from the positive sound; when it is used in the first playing, it is combined with the positive sound.
• Shi (Shi): Play the string with the right hand, and use the left hand to make a tease; if the right hand does not play, the left hand uses the tease to call the messenger in the sound of walking. After pressing the sound, point to one or two, and then make a chanting, and collide (even if it is), and return to the standard position.
• (Three tones): Press the string with the ring finger of the left hand, fold the big finger first, then fold it with the right hand, then fold it twice with the left hand, and finally fold it with the right hand, making a total of eight sounds.
• (Three sounds of folding, pulling and stabbing): Same as the previous example, but this time, instead of pinch, poke is used.
