The chiral theory of mesons of two flavors has been extended to mesons containing strangeness. The theory has been studied at the tree level. Two new mass relations between vector and axial-vector mesons have been obtained. In the chiral limit, the physical processes of normal parity and abnormal parity have been studied. Because of the universality of the coupling of this theory many interesting results have been obtained. In the chiral limit, theoretical results are in reasonable agreement with data.
