Abstract　 　　
　Supernovae represent the death of stars, and are one of the most energetic explosive events in the universe. They are related to diverse aspects in astrophysics, e.g., from stellar evolution to chemical enrichment of the universe. In particular, type Ia supernovae play an important role in observational cosmology. In this talk, I will introduce the supernova search that we are conducting with some small-size telescopes in China. Our project has led to the discovery of nearly 80 supernovae and lots of other transient sources (e.g., novae, variables, and AGNs) during the first 1.5-year survey. I will also describe the follow-up observations of supernovae and present some preliminary science results from our survey.
