Well, I decided to try.
I poured out the vegetable juice of the original fried green peppers pickled in qianzi, washed two green peppers and cut them into sections for later use, then poured some vegetable oil into the pot and put the spare green peppers into the pot for stir-frying. When it is 80% ripe, put the original green pepper fried in qianzi into the pot, and add a proper amount of water to stir fry together. When it was almost finished, it was served. When I tasted it, qianzi was still a little salty. Then I poured out the vegetable juice, stir-fried it with clear water and tasted it again. This time, the salinity is much better than before. This plate of fried green pepper dry brine is not wasted. It's finished.
Then in the future, if the food is salty, you can handle it like this. I think it still works.
