Correction to the questioner: This piece is not originally a guzheng piece. This piece is cheerful and played with strings, erhu, pipa, and qudi to reflect the unique mood of Jiangnan (Suzhou).
The familiar "Purple Bamboo Dialogue" is performed by a peasant girl from Suzhou's Jiangnan water town in the form of beating lotus flowers, which brings a different feeling to the audience.
"Zizhu Tune" was originally a popular love ditty in Suzhou in the 1930s and 1940s, and later became a Shanghai opera tune. After being disseminated and modified by generations of artists, it has become a subtle and interesting love song. The music uses strings, erhu, pipa, and qudi to play the melody, and the crystal arpeggios of the harp complement it, which is quite the style of Jiangnan silk and bamboo. The lyrics are often inspired by emotion and there is no fixed version. This is also a characteristic of folk songs in their most primitive state.
