  We consider two explicit constructions of states in the orbifolds of a
product of Minimal $N=(2,2)$ models which are based on twisting by spectral
flow, mutual locality and operator algebra requirement. It is shown that these
two constructions lead to the Berglund-Hubsh-Krawitz dual orbifold groups which
define mirror pairs of isomorphic models. Then we generalize our construction
for the orbifolds of Gepner models of superstring compactification and
explicitly build IIA/IIB mirror map of the space of states of the superstrings
using light-cone gauge.
