Piano and cello are intertwined, haunting melancholy atmosphere, combining the classic styles of Ludovico Aaudi, Oraf Arnaldes, Max Richter and Li Runmin. This is an emotionally charged film piano piece with a contemplative quality that is suitable as a documentary soundtrack. In the development of piano and strings, the music gradually transitions from a sad tone to a hopeful ending. The rhythm is full of changes: the opening 180 BPM,1:47 – 2:23 drops to 130 BPM (slow passage), and 2:23 – 2:29 rises to 165 BPM.
