They definitely should.
In fact, I'd go further and say that they should also consider having more than one site for their production work, whether that means having sites in the same city (but in different locations with some distance between the two) or within a metropolitan region, or even in different cities elsewhere. Having too much production capacity bundled at just one location could introduce serious vulnerabilities, especially during wartime.
This similarly applies to the other ACs under the AVIC umbrella. Maybe we're seeing this starting to happen with Shenyang, though I'm not exactly sure whether this is actually true.
Previously, it made sense to disperse production capacity because bombs were unguided.
If you concentrated production facilities, you created a larger area target which was easier to hit.

But now, accurate, guided weapons are low-cost and are the norm.
Dispersing production capacity also means dispersing defensive systems like SAMs.
So instead of having 2 separate facilities, better to just have them next to each other, and where you can concentrate all the defensive systems.
Dispersing facilities will also be inefficient, increasing costs and production times. So you get less production for your money during a peacetime buildup.
