  We present a new method for reconstructing CFT duals of states excited by the
bulk local operators in the three dimensional AdS black holes in the AdS/CFT
context. As an important procedure for this, we introduce a map between the
bulk points in AdS and those on the boundary where CFT lives. This gives a
systematic and universal way to express bulk local states even inside black
hole interiors. Our construction allows us to probe the interior structures of
black holes purely from the CFT calculations. We analyze bulk local states in
the single-sided black holes as well as the double-sided black holes.
