I've seen a lot recently. Basically at 1-2, there is one sortie, sometimes one, sometimes three, and at most four planes fly in formation at the same time! Basically, the sky is full of the roar of planes during the day and night, and I also have photos and video records. They must be soldiers, but I don't know what type they are. I've seen hundreds of them in the past two days. I don't know if it's just a few round trips or a large number of planes changing places! Looking forward to an answer! ! I went to the yard one by one, and after several times, several times all day, I could hear loud voices until the evening!
