Origin Story
在战国时期，七雄争霸，战火不断。秦国经过多年苦心经营，终于打败了六国，统一了中国。但秦朝的统治基础并不牢固，社会矛盾重重，百姓生活困苦，民怨沸腾。秦始皇为了维护自己的统治，实行残酷的统治手段，导致民心尽失。同时，秦始皇还大兴土木，建造了奢华的宫殿和陵墓，耗费了大量的人力物力，加剧了社会矛盾。最终，秦朝只维持了短短的十五年便轰然倒塌。秦朝的覆灭给后人留下了深刻的教训：一个国家要长久稳定，必须重视民生，实行仁政，否则，就会像秦朝一样，千疮百孔，最终走向灭亡。
During the Warring States period, the seven great powers competed for dominance, and the war continued. After years of hard work, the Kingdom of Qin finally defeated the six other kingdoms and unified China. However, the Qin Dynasty's rule was not stable, social conflicts were rampant, people lived in poverty, and resentment was boiling. Qin Shi Huang, in order to maintain his rule, implemented cruel methods of rule, leading to the loss of popular support. At the same time, Qin Shi Huang launched large-scale construction projects, building luxurious palaces and tombs, consuming a large amount of manpower and material resources, and exacerbating social conflicts. Eventually, the Qin Dynasty lasted only 15 years before it collapsed. The demise of the Qin Dynasty left a profound lesson for future generations: a country can be stable for a long time only if it attaches importance to people's livelihood and implements benevolent governance, otherwise, it will be riddled with holes, like the Qin Dynasty, and eventually head towards destruction.
