This doesn't look quite right to me.  According to the holdings table
in the wiki:

https://wiki.koha-community.org/wiki/Holdings_data_fields_(9xx)

952$a and 952$b should contain the branch codes for owning library
and holding library, respectively.  Your 952$a doesn't look like
a branch code, and I don't see a 952$b.

When I imported our Mandarin catalog to Koha, my script set the following
rather minimal holding fields, and that seemed to be enough:

 942$c - item type
 952$8 - collection code
 952$a - owning library
 952$b - holding library
 952$c - location code
 952$d - acquisition date
 952$o - call number
 952$p - barcode
 952$v - price
 952$y - item type

Note that you need to have previously set up the authorized values for collection
codes and location codes for this to work.
