Origin Story
很久以前，在一个偏僻的小山村里，住着一位名叫阿牛的年轻樵夫。阿牛为人善良，勤劳朴实，但他却有着一个致命的缺点——粗心大意。 有一天，阿牛像往常一样上山砍柴。由于过于专注于砍柴，他并没有注意到脚下的小路越来越崎岖，最后，他竟迷路了！天色渐暗，山风呼啸，阿牛心中开始害怕起来。这时，他看到不远处有一座破旧的庙宇，便急忙跑了过去，想找个地方躲避风雨。 庙宇里供奉着一尊破损的神像，神像前的地上散落着一些零碎的古董碎片。阿牛好奇地捡起一块碎片，发现这块碎片竟然是一块精美的玉佩的一部分。他仔细观察周围，又找到了几块玉佩碎片，竟然拼凑成了一整块完整的玉佩！ 阿牛惊喜万分，他从未想过自己会误打误撞地找到这块价值连城的玉佩。他将玉佩带回村庄，交给村长，村长经过鉴定，证实这块玉佩是失传已久的珍宝。阿牛因为误打误撞的发现，受到了全村人的赞扬，他的生活也因此发生了翻天覆地的变化。
Long ago, in a remote mountain village, there lived a young woodcutter named An Niu. An Niu was a kind, hardworking, and simple man, but he had one fatal flaw—carelessness. One day, An Niu went to the mountains to chop wood as usual. Because he was so focused on chopping wood, he didn't notice that the path under his feet was becoming increasingly rough, and finally, he got lost! As night fell and the mountain wind howled, An Niu's heart began to pound. At this moment, he saw a dilapidated temple not far away, and he quickly ran over, wanting to find a place to shelter from the wind and rain. In the temple, there was a damaged statue, and scattered on the ground in front of the statue were some broken pieces of antique. An Niu curiously picked up a piece of the debris and found that it was actually part of a beautiful jade pendant. He carefully examined the surroundings and found several more pieces of jade pendants that made up a complete pendant! An Niu was overjoyed. He never expected that he would stumble upon this priceless jade pendant. He took the pendant back to the village and gave it to the village head. After verification, the village head confirmed that this pendant was a long-lost treasure. An Niu, because of his accidental discovery, was praised by everyone in the village, and his life changed dramatically as a result.
