  In this work, we introduce the hadronic loop contribution to explain the
anomalous radiative transitions between $h_b(nP)$ and $\eta_b(mS)$, which was
recently observed by the Belle Collaboration. Our calculation shows that the
hadronic loop mechanism associated with these known decay mechanisms can
explain why there exist anomalous radiative transitions between $h_b(nP)$ and
$\eta_b(mS)$. This study deepens our understanding of the decay mechanism of
higher bottomonium radiative decays.
