  Correct identification of the true gauge symmetry of General Relativity being
3d spatial diffeomorphism invariant(3dDI) (not the conventional infinite tensor
product group with principle fibre bundle structure), together with intrinsic
time extracted from clean decomposition of the canonical structure yields a
self-consistent theory of quantum gravity. A new set of fundamental commutation
relations is also presented. The basic variables are the eight components of
the unimodular part of the spatial dreibein and eight SU(3) generators which
correspond to Klauder's momentric variables that characterize a free theory of
quantum gravity. The commutation relations are not canonical, but have well
defined group theoretical meanings. All fundamental entities are dimensionless;
and the quantum wave functionals are preferentially in the dreibein
representation. The successful quantum theory of gravity involves only broad
spectrum of knowledge and deep insights but no exotic idea.
