"Wood Language" echoes the heroine Su Muxia's identity as a cultural relic restorer, implying her craftsman qualities of "dialogue" with old wood; "Building Heart" corresponds to the hero Lu Yu's career as an architect, reflecting his pursuit of using design to build space and emotional connection. The overall title of the book not only highlights the professional differences between the two, but also hints at the romantic main line of "using wood as a matchmaker and staying together with heart", and at the same time "mortise and tenon meets design" The contrast, with its own tension of collision between tradition and modernity, can attract readers who like urban emotions and career growth themes.
