The quasi-excitations of quantum Hall systems at the filling factor ν = p/(2pq ± 1) are studied in terms of chargeon and fluxon introduced previously as constituents of an electron at ν = 1/2. At temperatures T < T_<PFS>(ν), the particle-flux separation phenomenon takes place, and chargeons and fluxons are deconfined to behave as quasiparticles. Bose condensation of fluxons justifies the (partial) cancellation of external magnetic field. Fluxons describe correlation holes, while chargeons describe composite fermions. They contribute to the resistivity ρ_<xy> = h/(νe^2) additively.
