#### Abstract

We study the relation among the genus $0$ Gromov-Witten theories of the three spaces $\mathcal{X}\leftarrow\mathcal{Z}\leftarrow Y$, where $\mathcal{X}=[\mathbb{C}^2/ \mathbb{Z}_3]$, $\mathcal{Z}$ is obtained by a weighted blow-up at the stacky point of $\mathcal{X}$, and $Y$ is the crepant resolution of the $A_2$ singularity. We formulate and verify a statement generalizing the Crepant Resolution Conjecture of Bryan and Graber, that we call the Crepant Partial Resolution Conjecture.
