Hu Ting-yi works as a movie sound technician and foley artist. Looking for props to help him make suitable effects is the first part of his job. He collects fruit, vegetables, pots, pans, and bits of scrap metal to create the sounds he will need to accompany the action on screen. Hu says the role of a foley artist is not well known, but it is his job to express the actor's emotions and mood through sound effects.
