Origin Story
战国时期，楚国诗人屈原，是一位爱国主义者，他主张联齐抗秦，遭到了一些贵族的反对，被楚怀王流放到边远地区。虽然被流放，但屈原始终没有放弃自己的理想，依然心系国家和人民，写下了著名的《离骚》等作品，表达了自己的爱国情怀。在《离骚》中，屈原写道：“亦余心之所善兮，虽九死其犹未悔。”意思是说，即使要经历九死一生的磨难，也决不后悔自己所做的一切。
During the Warring States Period, Qu Yuan, a poet from the State of Chu, was a patriot who advocated for an alliance with the State of Qi to resist Qin, but he was opposed by some nobles and was exiled to a remote area by King Huai of Chu. Although he was exiled, Qu Yuan never gave up his ideals and was still concerned about his country and people. He wrote famous works such as "Li Sao", expressing his patriotic sentiments. In "Li Sao", Qu Yuan wrote: "Even if I die nine times, I will not regret what I have done." This means that even if he had to go through nine deaths and one life, he would never regret what he had done.
