  In this paper, we would like to study operator reconstruction in a class of
holographic tensor networks describing renormalization group flows studied in
arXiv:2210.12127. We study examples of 2d bulk holographic tensor networks
constructed from Dijkgraaf-Witten theories and found that for both
$\mathbb{Z}_n$ group and $S_3$ group the number of bulk operators behaving like
a generalized free field in the bulk scales as the order of the group. We also
generalize our study to 3d bulks and found the same scaling for $\mathbb{Z}_n$
theories. However, there is no generalized free field when the bulk comes from
more generic fusion categories such as the Fibonacci model.
