Starting from the Imperial Book of Classics

An ordinary high school student is about to usher in the most important moment of his life. He returns to his grandfather's courtyard. Under the floor tiles of the ancestral hall are filled with inherited secrets. After a thousand years of waiting, he must put everything aside and return to his hometown, a place he has never heard of. The green mountains are together with the clouds and rain, but the bright moon has never been the two villages.
