  Constructing the corresponding geometries from given entanglement entropies
of a boundary QFT is a big challenge and leads to the grand project \emph{ it
from Qubit}. Based on the observation that the AdS metric in the Riemann Normal
Coordinates (RNC) can be summed into a closed form, we find that the AdS$_3$
metric in RNC can be straightforwardly read off from the entanglement entropy
of CFT$_2$. We use the finite length or finite temperature CFT$_2$ as examples
to demonstrate the identification.
