The military training is bitter, so bitter that you feel you have been alienated from the society and even the world has become dark. The military training is tiring, so tiresome that it hurts when you take a breath, tiresome to the point that you want to sleep soundly and don't want to wake up in advance. The military training is also beautiful, so beautiful that you fall in love with the green uniform and don't want to take it off, so beautiful that you would rather suffer here than go home.
