The volume of the guzheng is large and the sound box is large, so the volume of the guzheng is also large, which is more in line with the taste of modern people. Guqin notation is in its own category. In ancient times, it was called character notation, and in the Tang Dynasty, it was called reduced character notation. In ancient times, guzheng often used Gongqi notation, but now it mostly uses simple notation and staff notation.
