I don't know where you come from. It's too hot in summer in Henan, and the temperature is around 40 degrees. Qiqihar and Jiamusi are too cold. Shenyang and Jinzhou are good choices. The ground service of Shenyang Air Force is not very tired (except for flight days, it gets up very early), and Jinzhou Army is also very good. If the 40 th Army is in the city, the artillery brigade will not be tired even if it is close to the city in the suburbs! I don't recommend choosing armed police. Most armed police are stationed in prisons or bridges. Training is hard every day, and they have to stand guard for 2 hours. The post from 2 o'clock to 4 o'clock is the hardest to stand (sleepy). .
