En Heng(Hmm) is a music video in the form of stop-motion animation, telling a story about a sperm's journey in pursuit of its soul mate. Not relying on any normal instrument, the music is made through a creative mixture and integration of sounds of real objects and human voices which are collected in people's daily life.
