贪心不足

很久以前，在一个繁华的集市上，住着一位名叫阿牛的年轻人。阿牛为人勤劳，靠着卖水果为生，日子虽然清贫，但也算过得安稳。一天，一位路过的富商看到阿牛的水果新鲜饱满，便大量收购，阿牛赚得盆满钵满。尝到甜头的阿牛，并没有满足于现状。他开始盘算着如何赚取更多的钱财。他把赚来的钱全部投入到更大的生意中，却因为经验不足，生意接连亏损，最终倾家荡产。阿牛的经历告诉我们，做人要知足常乐，切莫贪心不足蛇吞象，否则只会适得其反。

Long ago, in a bustling marketplace, lived a young man named A Niu. A Niu was hardworking and made a living selling fruit. Although his life was simple, he lived peacefully. One day, a wealthy merchant passing by saw that A Niu's fruits were fresh and plump and bought them in large quantities. A Niu earned a lot of money. Having tasted success, A Niu did not settle for the status quo. He began to think about how to make even more money. He invested all his money in a larger business but, due to lack of experience, suffered losses and eventually lost everything. A Niu's experience teaches us that one should be content with what one has and should not be greedy; otherwise, it will backfire.
