Origin Story
从前，在一个繁华的城市里，有一家名为“聚宝斋”的珠宝店，店内琳琅满目，吸引了众多顾客。一日，一位富商前来购买一枚价值连城的玉佩，店主热情地为其介绍，并开出了一个令富商满意的价格。然而，当富商准备付钱时，却发现自己带来的银票不够，于是便向店主商量是否可以先拿走玉佩，等明日再来支付尾款。店主却认为富商不诚信，不肯答应，双方因此争吵不休。最终，富商愤然离去，留下店主独自生闷气，最终不欢而散。
Once upon a time, in a bustling city, there was a jewelry store called "Treasure Pavilion", which was filled with dazzling treasures and attracted many customers. One day, a wealthy merchant came to buy a priceless jade pendant. The shopkeeper enthusiastically introduced it to him and offered a price that satisfied the merchant. However, when the merchant was about to pay, he realized that the silver notes he brought were not enough, so he asked the shopkeeper if he could take the pendant first and pay the balance the next day. The shopkeeper, however, believed that the merchant was untrustworthy and refused to agree. The two argued endlessly. In the end, the merchant left angrily, leaving the shopkeeper to stew in his own anger. They eventually parted ways in a bad mood.
