Saw one particular mention that the J-35's weapons bay is also largely similar in size as the J-20's weapons bay.
Assuming that the weapons bay depth is also similar for both the J-20 and J-35, then that means the J-35 can also carry 4x PL-15s inside its weapons bay (which could be upgraded to 6x if the PL-15's fins can be made foldable).
Another thing to note, though - While the weapons bay of the F-35 and J-35 has almost similar length - The F-35's weapons bay has been divided into two smaller halves on each side of the fuselage, while the J-35 has a singular large one.
It literally doesn't make any sense to make the bay different (other than larger, but that doesn't make too much sense either - b/c standardization). PLANAF doesn't have its own unique aircraft weapons line to even bother. Furthermore, given their position - i doubt the bay has any reason to differ in any case.
Same bay and same choice of munitions, developed for new standard size requirements. Maximum convenience.
F-35 bay isn't in
smaller halves, they're different in shape when compared to rectangular bays of other fighters. Somewhat shorter, but also significantly deeper. They were built around standard 2000 lb as a requirement, after all.
