Abstract：Bulk reconstruction in the AdS/CFT correspondence is aimed to construct the bulk physics from the information of the boundary CFT. In the first part of this talk, we will introduce our recent work on a surface growth approach to build up the bulk spacetime geometry, we will show that this formalism can be explicitly realized with the help of the surface/state correspondence and the one-shot entanglement distillation method , which provides a concrete and intuitive way for the entanglement wedge reconstruction. In the second part, we will give a new proof for the entanglement of purification by combining the ideas of the bit thread and the surface growth approach. In addition, by applying the locking theorem of bit threads, we also find a derivation for the partial entanglement entropy proposal.
