I bought a dinosaur book from the thrift store because my son really likes dinosaur. When we saw the book we are curious about the this page saying scan using app. We downloaded the app and try to scan the code. We are surprised because dinosaurs appeared on phone screen and it is also moving. Technology really replaced the traditional ways of studying. I was thinking what more technology can offer to us in the future. I hope Doraemon’s door will became reality in the future.
