This is a piece specially written for piano and guzheng. It's very nice, with bright and smooth melody and euphemistic tone. It depicts the lakes and mountains in the south of China, which is very poetic and expresses the author's feelings and love for natural scenery.
In the attachment, I sent you the score of this song (ove format) for your reference.
I don't know if you have Overture software installed. If you can't open the file, I suggest you download an Overture4.0 installation opening file from the Internet, and you can still listen to the complete music effect. )
