In the turbulent city of Feng'an, the rivers and lakes are raining at night, and the human relationships are warm and cold. Tiedan, a rough and tough country orphan; Xiaocao, a smart and clever street boy disguised as a man. An adventure of abduction and trafficking brings two lonely souls to each other.
They studied under their masters, and in the interplay of gongs, drums and three-stringed instruments, Xiaocao developed a unique skill and became famous throughout the city. Tiedan guarded her silently, eager to give her a free sky. But Vanity Fair is Shura Fair, and the claws of the powerful have reached out to the famous actors on the stage. For that loud applause, Xiaocao paid the price of his freedom and even his life. Tiedan's rescue was a step late, which made him play the never-ending song of Lihentian alone in troubled times with endless grief.
