The training period you refer to is pre-commission military training, which is not easy or difficult, as long as you have the will.

Including military training and physical training in the queue, it is definitely not suitable at first, because high school is not so strict, but everyone can stick to it. The consequence of failing the exam is to drop out of school, but you will never fail. That's a coward.

You are mainly faced with not only training, but also all the maladjustment of life. You get up at six o'clock every day, fold the quilt, do exercises and clean up, start training at eight o'clock, run or stand in the hot sun, continue after a nap, and watch news or political studies at night.

You may find it difficult, but it's just the initial maladjustment. Everyone can adapt, and the conditions are much better now.

Work hard.

Don't complain
