I am thinking more on the location of the airbases rather than the units.
Shanghai and Fuzhou bases are just by the side of the coast. Wuhu is about 300km inland. J-20 is a long legged fighter. J10, J7 are short legged fighter, J16, Su30MKK are bombers, only J11B is a long legged fighter.
Could it be that PLAF choose the location rather than unit because they want to have J-20 less exposed to signal collection by SIGNT? Less chance being spotted when taking off, then fly low, therefor more surprise to potential adversary?
