There are ~400 quasars at z > 5.7 are published. These high-redshift quasars provide unique labs to investigate the co-evolution of the first SMBHs and their host galaxies at the end of the re-ionization epoch. To study the co-evolution of the SMBHs and their host galaxies, there are two aspects, one is to find ways to improve the estimation of the mass of the central BHs, and the other is to investigate the host galaxy properties though the ISM such as the dust, molecular and ionized gas. There still some open questions in this field: Do these luminous quasars at the earliest epoch form through major galaxy mergers? What are the typical physical conditions and dynamics of the ISM in the nuclear region that is powered by both the luminous AGN and the intense star formation? How is the SMBH-bulge relationship established via host galaxy star formation and AGN feedback at early stage of evolution? We are trying to solve these problems from the aspact of quasar host galaxies.
