From the end of the 20th century to the middle of the 21st century, Chai Aolan, a young man from Chaijiapu in the northwest, became close friends with his Kazakh classmate Amir Yindombula at Fudan University. After graduation, the two fell apart. Chai Aolan went to Chongqing to start a business, while Amir returned to his hometown to inherit the skills of making and playing dombola. Many years later, a reunion at Chongqing's Binjiang Square allowed them to renew their childhood agreement - to use Dongbula as a bridge to connect the grassland and the mountain city.
With the participation of architect Lin Mo, the three of them jointly promoted the Dombula culture to take root in Chongqing: from public welfare teaching on the open-air stage to the establishment of the "Dombra Art Center"; from traditional performances to the integration of science and technology at the Metaverse Music Festival, to the successful application of the Kazakh Dombula art as a UNESCO World Heritage. Chai Aolan's son Chai Nian'an and Amir's daughter Zoya took over the baton and brought this ancient art to the international stage with the "Blue Sky Tambula Combination", allowing the sound of the piano to spread across the Jialing River and spread throughout the world.
The book ends with the opening of the "Chai Aolan Dongbula Art Memorial Hall" in 2045. The story of two generations and the love between two countries has become eternity in the sound of the piano and the years.
