As the most luminous non-transient objects, distant quasars are important tracers to study early structure formation and the history of cosmic reionization. However, recent studies suggest that the quasar density declines very fast towards to z>~7. I will introduce our dedicated survey of reionization-era quasars and present the quasar luminosity function measurement at z~7. I will also talk about the discovery of the new redshift record breaking quasar. In addition, I will discuss the predictions on quasar searching with the upcoming Nancy Grace Roman space telescope as well as the Rubin observatory.
