We clarify RR tadpole cancellation conditions for intersecting D4-/D5-branes.We find all of the D4-brane models which have D=4 three-generation chiralfermions with the SU(3)XSU(2)XU(1)^n symmetries. For the D5-brane case, wepresent a solution to the conditions which gives exactly the matter contents ofstandard model with U(1) anomalies.Comment: 6 pages, submitted to Progress Letter
