It might just boil down to tech/amount of people available. China may not have the anti-corrosive spray or there are so many maintenance personnel that they could get away with scrubbing with a sponge. Who knows.

Planes are left on the tarmac all the time when it snows and rains... Even with j10...

I don't see any corrosion problems affecting life span of aircraft of PLAN or PLAAF if they are properly maintained and parts replaced as per scheduled. Most of the aircraft are retired after their normal useful lives, and were already obsolete by then.
J6 , J7 and others were in serviced for their full life spans.
J10A has been in service in 2004, after 17 years we have not heard of any one of them retired. Using sponge means minimum water is used to wipe off any salt moisture or any contaiminates. Spraying with powerful jet of water might actually force the salt moisture into minute gaps.
There are many ways of doing anti-corrosion at different maintenance period. Wiping with sponge with clean water may be done after every flight. Anti-corrossion foam may be applied after every few weeks or months as per maintenance schedule instruction book. Skin panel inspection for corrosion may be done at every schedule minor maintenace. And MLU or major maintenace after certain years may replaced corroded weakened parts.

I believe China is extremely meticulous regarding safety. With 'so many maintenance personnel' it is to ensure every single square centimetre is properly inspected and cleaned, each and every time.
I knew a Sq Ldr (maintenance) from Karachi who mentioned to me that all aircraft are washed regularly with denatured water, due to corrosion concerns from the highly corrosive environment operating over Indian ocean. Apparently this was not SOP at other PAF bases.
This as 20 years ago and made sense to me.
So, basically, they're doing away with the JL-8 (the intermediate trainer) and going straight from the basic trainer to the JL-10. (advanced trainer). And they seem to be doing away with the JJ-7 as the last step and going from the advanced trainer to a J-10S? Is that the correct way to interpret this piece of news?
