When the iPhone 13 was released, I saw on the Internet that the camera of the iPhone was very similar to the traditional Chinese mahjong color. So I want to combine Chinese national quintessence mahjong with Western high-tech products to create a cultural collision work. Through my investigation of Western high-tech, I feel that Iron Man can interpret Western high-tech technology very well, so my work tells the process of fighting between Mahjong and Iron Man, and presents it in the form of a handmade book.
