Indeed, the logic of the phrase "backward will be beaten" is not so rigorous. It also shows a certain PTSD temperament and feels like it has broken steel teeth and patted all over the railings. But the practical significance of this sentence lies in its determination and absoluteness, which can cure most of the cartilage diseases and fantasies, and awaken a group of ostriches and small freshness. Behind this sentence are generations of people who have become bridges and roads, the most silent and turbulent cry, to eliminate all difficulties and seek development, to overcome difficulties and win.
