I have some wonderful collections in my bedroom, a necklace strung by colorful electrical resistances on shining soldering tin, a radio I took apart and assembled again and again. These little things, just like the old diary, recorded the stories of my childhood. I remember the inspiration from seeing my father create a phone and a radio with components taken from his university’s laboratory. It was just like a magic show! That sparked my passion toward solving practical problems with technical means. It led me to select electrical engineering as my major in the university.
