This talk will include an overview of recent observational research progress on fast radio bursts (FRBs). FRBs are mysterious millisecond pulses in radio, most of which originate from distant galaxies. Despite more than 50 theoretical models of FRB progenitors, their origin is still unknown. Therefore, revealing the origin of FRBs is becoming central in astronomy and astrophysics. After presenting some basic knowledge of FRBs, I will summarize the current observational constraints on the FRB progenitors. FRBs are expected to be useful cosmic probes to investigate key science in astronomy. I will overview how we can address key science using FRBs, including dark energy, dark matter, missing baryon problem, cosmic reionization, Hubble constant tension, testing general relativity etc. If time is allowed, I will briefly introduce a new FRB telescope plan in Taiwan: Bustling Universe Radio Survey Telescope in Taiwan (BURSTT).
