Changing the effective string length will change the vibration frequency of the strings, and further change the pitch of the emitted sound. When the effective string lengths on both sides of the konghou change synchronously, the current konghou uses two groups of support components to tighten the strings, respectively making the strings on both sides of the konghou taut, but the tightening degree cannot be balanced, which will reduce the tuning effect of the konghou.
