  We investigate the prospects for detecting axion-like particles (ALPs, dubbed
as "a") via the decay $Z\rightarrow a f\bar{f}$ at future $Z$ factories.
Considering the decay channels $a\rightarrow \mu^+ \mu^-$ and $a\rightarrow b
\bar{b}$ , four types of signals $\mu^+ \mu^- /E$, $b b /E$, $e^+ e^- \mu^+
\mu^-$ and $e^+ e^- b b$ are explored. We demonstrate that these channels are
promising for detecting ALPs at $Z$ factories and obtain the sensitivity bounds
on the couplings $g_{aZZ}$ and $g_{a\gamma Z}$.
