We study the edge states of fractional quantum Hall liquid at bulk filling factor with p being an even integer and . We describe the transition from a conductance plateau to another plateau in terms of chiral Tomonaga-Luttinger liquid theory. It is found that the fractional charge q which appears in the classical shot noise formula is on the conductance plateau at whereas on the plateau at it is given by . For and an alternative hierarchy construction is also discussed to explain the suppressed shot noise experiment at bulk filling factor .
