Origin Story
从前，有一个农民，他家的田地里长满了杂草，影响庄稼的生长。他听说了一种除草剂，据说能快速清除杂草，于是便购买了一大瓶。他按照说明书上的使用方法，将除草剂喷洒在田地里。起初，杂草确实枯萎了，农民感到很高兴。但是几天后，他发现不仅杂草死了，就连庄稼也枯萎了，最后颗粒无收。这次除草剂的使用对他来说，是有损无益的，白费了力气，还损失了粮食。
Once upon a time, there was a farmer whose field was overgrown with weeds, affecting the growth of his crops. He heard of a herbicide that was said to be able to quickly remove weeds, so he bought a large bottle. He followed the instructions on the manual and sprayed the herbicide on the field. At first, the weeds did wither, and the farmer was happy. However, a few days later, he found that not only the weeds died, but also the crops withered, resulting in a failed harvest. This use of herbicide was more harmful than good to him. He wasted his effort and lost his food.
