Once upon a time, there was a rich man named Kind-hearted Weng. He lived in the countryside of southern Taiwan. One day, he met a butcher leading a cow down the street. He asked the butcher, “Is this cow for sale?” The butcher replied, “This cow is on its way to be slaughtered.” Kind-hearted asked, “Can you sell it to me?” The butcher replied rudely, “It will cost you a lot of money, can you afford it?” Kind-hearted smiled and said, “Name a price.” The butcher asked for three thousand dollars, and Kind-hearted bought the cow without hesitation.

That night, Kind-hearted tied the cow to a tree outside his home. It was late at night, and everyone had fallen asleep, except for the cow. The cow opened her eyes wide, as if she heard something. Suddenly, she started to moo very loudly, “Moo! Moo! Moo!” She woke everyone from their dreams, and they came running out of the house wondering what happened. Suddenly, a huge earthquake rocked the earth. Then, there came a huge noise. Kind-hearted's house had collapsed, and everyone was too shocked to move. After the cow stopped mooing, Kind-hearted told the cow gratefully, “Our ancestors said that cows were the first to know about an upcoming earthquake! My dear cow! Thank you for saving us all!” The cow wagged its tail.

As the night was still dark, Kind-hearted and his family decided to lay out straw mats and sleep under the tree. Kind-hearted slept beside the cow. In his dream, Kind-hearted heard the cow say, “Master, thank you for saving my life! I would have been slaughtered if you didn't save me. Therefore, you are my savior!” Kind-hearted said, “No, it was you who saved my family!” The cow replied, “You are kind and benevolent and a very good man. I must repay your kindness!” Just then, a drop of dew fell onto Kind-hearted's face and woke him up. He turned his head and looked at the cow. Not only did he believe what the cow said, from then on, he cherished the cow even more.

很久以前，在臺灣南部鄉下，有一位叫翁慈心的富翁，他在路上遇到屠夫牽著一頭黃牛，慈心便問：「這一頭牛是不是要賣？」屠夫回答：「是要牽去殺掉的。」慈心問：「可以賣給我嗎？」。屠夫不客氣的說：「很貴的，你買得起嗎？」慈心笑笑說：「要多少錢？」屠夫開價三千塊，慈心就掏錢把牛買下來。

當天晚上，慈心把牛綁在屋外的大樹下，到了半夜大家都睡著，黃牛卻沒有睡，一直瞪大眼睛，好像聽到什麼聲音一樣。忽然間，黃牛像發瘋一樣不斷狂叫「哞！哞！哞！」把屋裡睡覺的人都吵醒了，大家急忙跑出來看。忽然，地牛大翻身，天搖地動，接著傳來一陣巨響，慈心家的房屋轟的一聲全垮了，大家嚇得呆在原地。黃牛安靜下來後，慈心激動的對黃牛說：「古人曾說，牛最先知道地震！大黃牛呀！感謝你救了我全家一命！」黃牛只是搖搖尾巴。

由於天還沒有亮，慈心全家便在大樹下鋪上稻草睡覺，慈心則躺在牛旁邊睡。睡夢中，慈心聽到黃牛對他說：「主人，我很感激你救了我一命，如果沒有遇到你，我早就被殺掉了。所以，你才是我的救命恩人！」慈心說：「你才是我家的救命恩人！」黃牛又說：「你心地善良又仁慈，是個大好人，我一定要報恩。」這時慈心的臉被露水滴到後醒過來，轉頭看看身邊的黃牛，他不但相信牛說的話，從此也更加愛護這頭黃牛了。
