Origin Story
话说三国时期，蜀汉丞相诸葛亮五次北伐曹魏，却屡战屡败，损失惨重。但他并未灰心丧气，而是总结经验教训，整顿军备，休养生息，最终再次率兵北伐，虽然仍未取得决定性胜利，但他重振旗鼓的精神，却令人敬佩。
It is said that during the Three Kingdoms period, Zhuge Liang, the prime minister of Shu Han, led five northern expeditions against Cao Wei, but was repeatedly defeated and suffered heavy losses. However, he did not lose heart, but summarized his experience and lessons, reorganized his military equipment, recuperated, and finally led his troops on a northern expedition again. Although he still did not achieve a decisive victory, his spirit of regrouping is admirable.
