Origin Story
话说唐朝时期，一位著名的诗人李白，因饮酒赋诗，才华横溢而闻名天下。一日，他与友人畅谈诗词歌赋，友人对李白的才华赞叹不已，并不断追问他创作的灵感来源及过程。李白只是微微一笑，说道："创作的灵感，源于生活，而又高于生活，其间妙趣，无庸赘述。"友人虽不解其中玄机，但深知李白的才情，便不再追问。李白的故事在后世广为流传，无庸赘述其精妙之处，足以说明艺术创作的奥妙往往难以言尽，只可意会不可言传。
In the Tang Dynasty, there was a famous poet named Li Bai who was known for his prolific writing and wine-inspired poems. One day, he was chatting with a friend about poetry, and his friend was full of admiration for his talent, repeatedly asking about the source and process of his inspiration. Li Bai simply smiled slightly and said:"The inspiration for my writing comes from life, yet it transcends life. The subtleties involved are self-evident." Even though his friend didn't quite understand, he knew Li Bai's talent and didn't pursue the question further. Li Bai's story has been widely circulated throughout history. The details of the story's profound meaning are self-evident, suggesting that the mysteries of artistic creation are often beyond words and can only be appreciated intuitively.
