  We study the reconstruction of bulk operators in the entanglement wedge in
terms of low energy operators localized in the respective boundary region. To
leading order in $N$, the dual boundary operators are constructed from the
modular flow of single trace operators in the boundary subregion. The
appearance of modular evolved boundary operators can be understood due to the
equality between bulk and boundary modular flows and explicit formulas for bulk
operators can be found with a complete understanding of the action of bulk
modular flow, a difficult but in principle solvable task. We also obtain an
expression when the bulk operator is located on the Ryu-Takayanagi surface
which only depends on the bulk to boundary correlator and does not require the
explicit use of bulk modular flow. This expression generalizes the geodesic
operator/OPE block dictionary to general states and boundary regions.
