  The present article is a continuation of QA/1303.4046, where we discussed the
classification of quantum groups with quasi-classical limit $\mathfrak{g}$ and
introduced a theory of Belavin-Drinfeld cohomology associated to any
non-skewsymmetric $r$-matrix. Depending on the form of the corresponding
double, there exists a one-to-one correspondence between gauge equivalence
classes of Lie bialgebra structures on
$\mathfrak{g}\otimes_{\mathbb{C}}\mathbb{K}$, where
$\mathbb{K}=\mathbb{C}((\hbar))$, and untwisted or twisted cohomology classes.
In the present paper we investigate twisted cohomologies for $sl(n)$ associated
to generalized Cremmer-Gervais $r$-matrices, and twisted cohomologies for
$o(n)$.
