In the mountains and fields, the sound of the shepherd's flute accompanies the cows as they sleep. A young man, A Niu, takes the cow as his companion and the ground as his mat, studying hard on the grassy field ridge. He has no sense of elegance and only knows how to farm and read. However, in troubled times, he weaves blood, tears and starlight into his pen and ink with his lonely courage and reverence for heaven and earth. Once he passed the imperial examination, he shocked the court with his policy of "taking the people as the first priority" and jumped from being a cowherd to becoming the number one scholar in a new subject. Facing the powerful powerful people, he questioned the world as a commoner, using the wisdom and original intention of a shepherd boy to break the situation, take revenge, and counterattack, and finally played a soul-stirring lament for the shepherd's flute in the court hall.
