On the abandoned stage in the Loess Plateau, Qin opera sounds every night.
Seventeen-year-old Chen Du fell in love with a female actor who was hanged in the Republic of China on a stormy night.
She sang for the dead souls, and he stayed in the world for her.
Only later did he realize that there were more than just dead people buried under the stage.
There is also a spirit of the old era that refuses to go away.
