Something big happened in Hohhot?

There is an air force training base near Bikeqi. As long as the weather is fine, they will practice flying. Our family has a farmland near Gouzi Sakamoto, and there are flying missions almost every day in summer, which is very noisy and disturbing the people. But farmers may be used to it, and I don't know if anyone will complain. So don't worry, it's no big deal, it's just a normal military exercise.
