Pulsars discovery is one of the important milestones in human understanding of the universe. In this paper, we briefly introduce the pulsar research of recent 55 years, including the verification of gravitational waves and general relativity, the findings of millisecond pulsars, pulsar periodic jumps, pulsar radio radiation efficiency, fast radio bursts and extragalactic pulsars. we look forward to the potential of the Chinese FAST telescope for the discovery of new types of special pulsars in the future, including black hole pulsar, sub-millisecond pulsar, and new double pulsar systems, which will lead to more accurate validation of gravitational wave experiments; the fine structure of pulsar radiation is also studied by FAST with high sensitivity and high precision, and the physical mechanism of pulsar radiation will be deeply understood.
