### Description

The large data sample accumulated by the Belle experiment at KEKB asymmetric energy $e^+ e^-$ collider provides opportunities to study charmonia (bottomonia) and charmonium-like (bottomonium-like) exotic particles. In this presentation, we report recent results on these topics from Belle, including searches for $B \to h_c K$, $B \to Y(4260) K$, $B \to X(3872/3915)(\to \chi_{c1}\pi^0) K$ and a new measurement of the $e^+e^-\to \Upsilon(nS)\pi^+\pi^-$ ($n=1,2,3$) cross sections at energies from 10.52 to 11.02 GeV.
