  We construct a new version for the 3-3-1 model based on $T_7$ flavor symmetry
where the left-handed leptons under $T_7$ differ from those of our previous
work while the $\mathrm{SU}(3)_C \otimes \mathrm{SU}(3)_L \otimes
\mathrm{U}(1)_X$ gauge symmetry is retain. The flavor mixing patterns and mass
splitting are obtained without perturbation. The realistic lepton mixing can be
obtained if both the direction of breakings $T_7 \rightarrow Z_3$ and $Z_3
\rightarrow \{\mathrm{Identity}\}$ are taken place in neutrino sector. Maximal
CP violation is predicted and CKM matrix is the identity matrix at the
tree-level.
