  We take the scalar, pseudoscalar, axialvector, vector and tensor diquarks as
the basic building blocks to construct the four-quark currents with implicit
P-waves, and investigate the hidden-charm-hidden-strange tetraquark states with
the $J^{PC}=1^{--}$ and $1^{-+}$ via the QCD sum rules in a comprehensive and
consistent way, and revisit the assignments of the $X/Y$ states, especially the
$Y(4500)$, $X(4630)$, $Y(4660)$, $Y(4710)$ and $Y(4790)$, in the tetraquark
picture.
