Dear Jibiao , the input looks OK (3 types of atoms and 8 atoms in total) but your k-grid is very coarse. For graphene I usually use a grid of 33 33 1 0 0 0 or finer. To see if the individual atoms are accounted for you can project the bands onto the DOS (PDOS) using projwfc.x which will give you atom and orbital resolved DOS!
