  Based on a previous study of deriving the chiral Lagrangian (CL) from QCD, we
illustrate the main feature of QCD predictions for the CL coefficients (CLC) in
certain approximations. We first show that, in the large-N(c) limit, the
anomaly part contributions to the CLC are exactly cancelled by certain terms in
the normal part contributions (NPC), so that the final results only concern the
remaining NPC depending on QCD interactions. We then do the calculation in a
simple approach with further approximations. The obtained CLC and quark
condensate are consistent with the experiments.
