Origin Story
汉高祖刘邦打天下，靠的是运筹帷幄，决胜千里，他的部下也是个个骁勇善战。有一天，刘邦带领军队去攻打项羽，眼看着就要胜利了，突然，项羽的军队杀出一条血路，反扑过来，气势汹汹。刘邦眼看形势不妙，赶紧下令，让士兵们后退。这时候，一位将军冲到刘邦面前，大声说道：“大王，我们现在士气正旺，为什么退兵？我建议我们继续进攻，一举拿下项羽！”刘邦却摇了摇头，说：“不可。现在项羽的军队虽然势单力薄，但他们孤注一掷，声势浩大，我们不能掉以轻心。如果我们贸然进攻，很可能会被他们反败为胜。现在我们先撤军，保存实力，然后再寻找机会。”将军听了刘邦的话，虽然不太理解，但还是命令士兵们撤军。就这样，刘邦退回了营地，重新部署兵力，准备再次进攻。几天后，刘邦终于找到机会，再次出兵攻打项羽，最终取得了胜利，获得了天下。
Emperor Gaozu of Han, Liu Bang, conquered the empire through strategic planning and decisive victories over thousands of miles. His subordinates were also all brave and skilled in warfare. One day, Liu Bang led his army to fight against Xiang Yu, and it seemed that they were on the verge of victory. Suddenly, Xiang Yu's army broke out of the crowd and struck back with great force. Liu Bang saw the dangerous situation and immediately ordered his soldiers to retreat. At this time, a general rushed in front of Liu Bang and shouted loudly: “Your Majesty, our morale is strong now, why are we retreating? I suggest that we continue to attack and defeat Xiang Yu in one fell swoop!” Liu Bang shook his head, however, and said: “No. Although Xiang Yu's army is small and weak now, they are fighting with everything they have, and their onslaught is enormous. We must not be careless. If we attack rashly, we could be defeated by them. Now let's withdraw and conserve our strength, and then look for another opportunity.” The general listened to Liu Bang's words, and although he didn't quite understand them, he ordered his soldiers to retreat. Thus, Liu Bang retreated to his camp, redeployed his troops, and prepared to attack again. A few days later, Liu Bang finally found the opportunity to attack Xiang Yu again, and ultimately achieved victory and gained the empire.
