Origin Story
很久以前，在一个风景如画的山谷里，住着一位名叫李山的老人。李山一生勤劳善良，虽然生活清贫，但他总是怡然自得。他喜欢在清晨时分，到山间采摘野花，欣赏日出。他会在溪边钓鱼，静静地享受着大自然的馈赠。即使面对生活的艰难困苦，他也能保持乐观的心态，从容应对。他从不抱怨命运的不公，因为他相信只要内心充满阳光，就能战胜一切困难。邻居们都羡慕李山的乐观和豁达，称赞他拥有着一种让人难以企及的幸福。李山常说，幸福不在于拥有多少财富，而在于拥有一颗平静而满足的心。他用自己的行动诠释了“怡然自得”的真正含义，也为世人留下了宝贵的精神财富。
Long ago, in a picturesque valley, lived an old man named Li Shan. Li Shan was hardworking and kind all his life, although his life was poor, he was always content. He loved to pick wildflowers in the mountains in the morning and admire the sunrise. He would fish by the stream, quietly enjoying the gifts of nature. Even in the face of life's hardships, he could maintain an optimistic attitude and cope calmly. He never complained about the injustice of fate, because he believed that as long as his heart was full of sunshine, he could overcome all difficulties. His neighbors envied Li Shan's optimism and open-mindedness, praising him for having a happiness that was hard to match. Li Shan always said that happiness lies not in how much wealth you have, but in having a peaceful and content heart. He used his actions to interpret the true meaning of "怡然自得", and left valuable spiritual wealth for the world.
