The traditional winding procedure is to wind the fifth string first, followed by the sixth string and the seventh string, and these three strings are tied to a goose foot on the right one by one. The method of tying is to hold the string from the middle of the two wild goose feet against the wild goose feet and wind them from the inside. Then the first, second, third, and fourth strings are tied to a goose foot on the left one by one. The tie method is the same as that of the fifth, sixth and seventh strings. This is because the seventh and fourth strings are used more often, and the strings are easy to break, and the rear top is tied to the outside for easy replacement.

Since the five strings are played first, the pitch of the five strings must be determined first. Therefore, the tension program on the five strings is to match the sound of the second hole of the dongxiao's self-blowing mouth, that is, the first hole of the first hole. is the degree, which is equivalent to the sound of the A tube of the Western music timbre. This is the degree of neither loose nor tight. If it is looser than this, the first string will be too slow and silent. If it is tighter, the seventh string will be too fast and easy to break.

According to this standard, the well-tuned seven strings are the positive tuning of the three strings. (Equal to the key of F in Western music), after the fifth string is aligned, the sixth string is placed next, and its tightness is measured by pressing the fifth string and twelve emblems with the left index finger, pulling the sixth string with the big finger, and pressing the fifth string. Are the two corresponding? (Correspondingly, one press and one loose, the two strings sound at the same time, and the word Xianweng is formed, that is, the two strings have the same degree of sound.) If the twelve emblems should not be placed on the emblem, the six strings should be too tight and should be loosened. If it should be under the emblem, the six strings should be too loose and should be tightened, and it must be required that it should be under the twelve emblems.

Following the seventh string, press the six strings and the thirteen emblems to respond, and the test strings are the same as the sixth strings. The fifth, sixth, and seventh strings are finished, and then the strings are wound again, that is, pressing the first string and the thirteen emblems corresponds to the dispersion of the seventh string. If it should be on the emblem, the first string should be tight, and if it should be under the emblem, the first string should be loose. This is because what is pressed is the later, undetermined string, so it is opposite to the previous test of the sixth and seventh strings.

On the second string, press the thirteen emblems of the first string and the second string to disperse the sound. The test method is the same as that of the sixth and seventh strings. Following on the three strings, press the two strings and twelve emblems and the three strings to disperse the sound. At the end of the four strings, press the three strings and the thirteen emblems to respond to the four strings, and the audition is the same as the six or seven strings.

So the seven strings are all done, but when the new string is started, its nature is uncertain, and it is easiest to loosen. It is best to go on twice in a row in one or two days, and it will be qualitative. Or it is even better to use a tool to tighten the string for a few days to make it qualitative, and then put it on again.
