Now Do You Know Who I Am seems like a book of numbers, yet the plot involves elements of detective genre. While reading, the reader needs to take the initiative to read the text and image as a whole. With the hints offered by the text, one has to carefully compare, judge, and choose what crossovers from fifteen richly-detailed spreads so as to answer the question from the book title. In the process of searching, one can lean the humor from pictures with well-hidden details. The color collocation is harmonious and subtle. The shapes and lines of the background, such as flower and grass, water waves, cloud shades, stone plates and stone bridges, have regular yet changing patterns and nuanced color variation. These features not only form the images but also give out an exuberant and buoyant atmosphere, which make reading a delightful visual feast.
