  We study the structure of higher genus Gromov-Witten theory of the quotient
stack $[\mathbb{C}^n/\mathbb{Z}_n]$. We prove holomorphic anomaly equations for
$[\mathbb{C}^n/\mathbb{Z}_n]$, generalizing previous results of
Lho-Pandharipande arXiv:1804.03168 for the case of
$[\mathbb{C}^3/\mathbb{Z}_3]$ and ours arXiv:2211.15878 for the case
$[\mathbb{C}^5/\mathbb{Z}_5]$ to arbitrary $n\geq{3}$.
