This is a pure music with the flavor of ancient civilization. In duduuk’s whimper, we seem to pass through the relics of civilization that have been lost for thousands of years. This once glorious city can still imagine the scenes of some people’s lives thousands of years ago. At the moment, only some ruins are left standing quietly. We walking among them cannot say whether we are regretful, lost or other feelings, it is suitable for use in scenes such as film and television dramas, documentaries, games, etc. This song is a seamless loop.
