History is like an ancient painting that has been framed layer by layer. The original and the copy are intertwined, and the truth is often covered up by the frames. This story begins with a rainy night, a scroll, and a desperate mission. In the fog of the capital city during the Wanli Year, we try to find those "cannot be faked" things that are wrapped up in layers of power, secrets, and time - whether it is the meaning of the painting or the faith deep in the heart. I hope that in this world where it is difficult to tell the truth from the false, we can all become those who "have clean hands and clean hearts".
