With the non-universal validity of the QPB that has been replaced by the complete QCPB, as a result, we reconsider the Ozawa's inequality in light of the QCPB that improves the Ozawa's inequality and leads to some further useful results associated with the environment variable in the quantum geometric bracket. It certainly demonstrates a fact that environment coupling terms are unavoidable for the revision of the Ozawa's inequality under the perspective of the quantum geomertainty relation. More importantly, the modified Ozawa's inequality can greatly improve the quantum experimental precision, in this way, we can test and verify the validity of the quantum geomertainty relation.
