Origin Story
很久以前，在一个繁华的城市里，住着一位名叫李大明的富商。他做生意很有头脑，赚了不少钱，也拥有了许多朋友。但是，李大明有个毛病，就是遇到困难就一走了之。 有一天，李大明和朋友们一起去郊外游玩，他们来到了一条河边。李大明想下河游泳，却不小心滑倒，掉进了水里。朋友们纷纷跳下河去救他，李大明却抓住了一块木头，拼命地向岸边游去。朋友们见他如此自私，都气愤不已，纷纷离开了他。李大明终于游上了岸，他却独自离开了，没有顾及那些救过他的朋友。 李大明一走了之，朋友们都对他失望透顶，再也没有人愿意和他来往。李大明也因此失去了朋友，也失去了生意上的伙伴，最终落得个孤独无助的下场。
Long ago, in a bustling city, lived a wealthy merchant named Li Daming. He was a shrewd businessman and made a lot of money. He also had many friends. But Li Daming had a flaw: he would simply walk away when he encountered difficulties.
