In the video, a person is seen flipping through a book. The book appears to be a guide or manual of some sort, with various images and text on the pages. The person's hand is visible as they turn the pages, revealing different sections of the book. The images on the pages seem to be related to construction or design, with some images showing different types of roofing materials and others showing windows and shutters. The text on the pages is too small to read, but it appears to be providing information or instructions related to the images. The person's hand moves quickly, indicating that they are skimming through the book rather than reading it in detail.
