Notably that batch of Guowang was built by private company Galaxy (Yinhe) Space, they're the third manufacturer for Guowang (alongside CASC subsdiary CAST and CAS offshoot SECM) and the first private one,it must be reminded that Guowang is more of a mix between the SDA constellation and Oneweb, a multiple provider dual use but non-mass-public constellation.

Galaxy space has been around for almost a decade but I don't think they've ever serially produced satellites before, although they've been somewhat regularly launching demonstration satellites, notably for Guowang demonstrations, lately one on the 1st CZ-12 Launch and another DtC demonstration satellite in April.

As far as I can tell the Guowang production lines are located:
Tianjin for CAST
Eastern Shanghai for SECM
Nantong in eastern Jiangsu for Galaxy Space
With a "superfactory" in construction in Wenchang (multi user but likely for CAST)
