Chen Mo, an introverted and sociophobic doctoral student in the Department of Architecture, accidentally traveled to a parallel world and became an apprentice in the restoration of ancient buildings. He just wanted to live an ordinary life of quiet meditation and playing the guqin, but due to repeated "accidents", starting from the restoration of an endangered ancient stage, he was involved in the torrent of cultural renaissance. The mortise and tenon structure he inadvertently restored became a hot search, the Tang Qin he repaired was astonished by musicians, and the Guqin music he improvised for the documentary became an annual hit... Faced with the swarming media, capital and admirers, Chen Mo just wanted to return to his construction site: "It's nothing, our ancestors have played with it a long time ago." But what he restored was not just buildings, but also the memory gap of this era's tradition. And the young director Lin Wei, who raised his camera to record all this, gradually discovered that this man who always wanted to hide carried more time than the images.
