  Let $X:=\{X(t)\}_{t\ge0}$ be a
  generalized fractional Brownian motion (GFBM) introduced by Pang and Taqqu
(2019): $$
  \big\{X(t)\big\}_{t\ge0}\overset{d}{=}\left\{ \int_{\mathbb R}
\left((t-u)_+^{\alpha}-(-u)_+^{\alpha} \right)
  |u|^{-\gamma} B(du) \right\}_{t\ge0}, $$ with parameters $\gamma \in (0,
1/2)$ and $\alpha\in \left(-\frac12+ \gamma , \, \frac12+ \gamma \right)$.
  Continuing the studies of sample path properties of GFBM $X$ in Ichiba, Pang
and Taqqu (2021) and Wang and Xiao (2021), we establish integral criteria for
the lower functions of $X$ at $t=0$ and at infinity by modifying the arguments
of Talagrand (1996). As a consequence of the integral criteria, we derive the
Chung-type laws of the iterated logarithm of $X$ at the $t=0$ and at infinity,
respectively. This solves a problem in Wang and Xiao (2021).
