Su Xiaotang, a "wild" cultural blogger who has amassed three million fans by gossiping about ancient books, makes boring ancient book knowledge as exciting as watching TV dramas. However, he overturned during a live broadcast - he mistakenly mistook the Daoguang engraving as a Qianlong treasure, and was also online checked by anonymous netizens for counterfeiting. What made her even more frustrated was that this netizen turned out to be Lu Jingchen, a top-notch person in the industry and the "living dictionary" of the ancient book restoration room of the old library. In order to save face and gain access to the master's professional knowledge, Su Xiaotang started the "breakfast feeding + question bombing" dual strategy mode. Every day, he stayed in the repair room with his homemade breakfast, asking questions from "how to adjust this paste" to "how to look at this paper texture". He suddenly turned Lu Jingchen, who was so cold that he could freeze the air, into a "dedicated consultant" who would take the initiative to leave hot milk for her and help her change the live broadcast script. In the process of restoring the manuscripts of the Republic of China and organizing ancient book archives, a carefree "funny girl" blogger and an extremely rigorous "veteran cadre" restorer went from being dissatisfied with each other to relying on each other. In the end, they not only protected the precious ancient book culture together, but also lived a sweet daily life filled with the fragrance of ink and fireworks.
