A song "Ode to Sadness" and a section of yellow sand road. The sun is far away from Cangshan Mountain, and the smoke is flying in the desert.
Linglong learned pipa music at a young age. After her family was wiped out, she joined her aunt in a singing and dancing studio, but she was free from worries. When the musician Linglong becomes the princess Liu Jun, crises follow one after another. When will the hatred between family and country end? When all the yellow sand has fallen away, there is only a song of resentment left in the pipa.
