  The Schwarzschild singularity's resolution has key values in cracking the key
mysteries related with black holes, the origin of their horizon entropy and the
information missing puzzle involved in their evaporations. We provide in this
work the general dynamic inner metric of collapsing stars with horizons and
with non-trivial radial mass distributions. We find that static central
singularities are not the final state of the system. Instead, the final state
of the system is a periodically zero-cross breathing ball. Through 3+1
decomposed general relativity and its quantum formulation, we establish a
functional Schr\"odinger equation controlling the micro-state of this breathing
ball and show that, the system configuration with all the matter concentrating
on the central point is not the unique eigen-energy-density solution. Using a
Bohr-Sommerfield like "orbital" quantisation assumption, we show that for each
black hole of horizon radius $r_h$, there are about
$e^{r_h^2/\ell^2_\mathrm{pl}}$ allowable eigen-energy-density profile. This
naturally leads to physic interpretations for the micro-origin of horizon
entropy, as well as solutions to the information missing puzzle involved in
Hawking radiations.
