  The three-body systems $\eta K^* \bar{K}^*$, $\pi K^* \bar{K}^*$, and $K K^*
\bar{K}^*$ are further investigated within the framework of fixed-center
approximation, where $K^* \bar{K}^*$ is treated as the fixed-center,
corresponding to the possible scalar meson $a_0(1780)$ or the tensor meson
$f_2'(1525)$. The interactions between $\eta$, $\pi$, $K$, and $K^*$ are taken
from the chiral unitary approach. The resonance structures appear in the
modulus squared of the three-body scattering amplitude and suggest that $\eta /
\pi / K$-$(K^*\bar{K}^*)_{a_0(1780)/f'_2(1525)}$ hadron state can be formed. By
scattering the $\eta$ meson on the fixed-center $(K^* \bar{K}^*)_{a_0(1780)}$,
it is found that there is a distinct peak around 2100 MeV, as shown in the
modulus squared of the three-body scattering amplitude, which can be associated
with the meson $\pi(2070)$. For the scattering of the $\eta$ meson on the $(K^*
\bar{K}^*)_{f_2'(1525)}$, a resonance structure around 1890 MeV is found and it
can be associated with the $\eta_2(1870)$ meson. Other resonance structures are
also found and can be associated with $\pi_2(1880)$ and $\eta(2010)$.
