The construction of the guzheng in relation to heaven and earth

It can be said that there are sun, moon and heaven and earth on the guzheng instrument. The guzheng is generally three feet, six inches and five inches long, representing 365 days in a year.

The guzheng is a multi-stringed, multi-column plucked musical instrument, similar in shape to a long box-shaped, slightly concave at both ends, with a three-dimensional base plate, a wooden box with zheng strings taut on the panels, and zheng code settled under each string.
