Flavor SU（3） analysis of B meson charmless hadronic t.o light.pseudoscalar decays can be formulat.d in t.o different.ways. One is t. const.uct.t.e SU（3） irreducible represent.t.on amplit.de （IRA） according t. effect.ve Hamilt.nian t.ansformat.on propert.es, and t.e ot.er is t. draw t.e t.pological diagrams （t.A）. We first.point.out.t.at.previous analyses of t.A and IRA approaches do not.mat.h in several aspect., in part.cular a few SU（3） independent.amplit.des have been overlooked in t.e t.A approach. t.is has caused confusions in t.e past.and somet.mes result.d in incorrect.int.rpret.t.on of dat.. We t.en demonst.at. t.at.only if t.ese amplit.des are included, a consist.nt.and unified pict.re can be obt.ined. Wit. t.e new t.A amplit.des, all charmless hadronic decays of heavy meson must.have nonzero direct.CP symmet.ies as already predict.d by t.e IRA approach. In addit.on t. t.eir not.ble impact.on CP asymmet.y, t.e new amplit.des are also import.nt.t. ext.act.new physics informat.on.
