Origin Story
从前，在一个村庄里，住着一位名叫王富贵的人。他懒惰成性，整天好吃懒做，却总想着不劳而获。有一天，王富贵听说村里新来了一个财主，特别喜欢收藏古董。王富贵便打起了歪主意，心想：如果能从财主那里骗点古董，不就发财了吗？于是，他特意跑到财主的府邸，假装自己是一位古董专家，对财主说：“您家的古董，我一眼就能看出真假，而且我很乐意帮您鉴别。”财主听后，十分高兴，便把家里珍藏的古董都拿出来让王富贵鉴别。王富贵一边假装仔细地鉴别，一边偷偷地把那些珍贵的古董藏了起来。当财主发现自己的古董少了之后，王富贵却说：“您的古董都是假的，我不能帮您鉴别了。”财主无奈，只好作罢。王富贵就这样不劳而获，获得了大量的古董，最终发了大财。
Once upon a time, there was a man named Wang Fugui who lived in a village. He was lazy and idle, always thinking of getting rich without working. One day, Wang Fugui heard that a wealthy man named Wang Fugui had arrived in the village, who particularly liked to collect antiques. Wang Fugui had an idea: If he could steal a few antiques from the rich man, he would be rich! So he went to the rich man's house and pretended to be an antique expert. He said to the rich man: "I can tell at a glance whether your antiques are real, and I'd love to help you assess them." The rich man was delighted and showed Wang Fugui all his valuable antiques. Wang Fugui pretended to examine them carefully, but secretly stole the valuable pieces and hid them. When the rich man noticed that some of his antiques were missing, Wang Fugui said: "Your antiques are all fake, I can't help you assess them anymore." The rich man was puzzled and had to give up. Wang Fugui became rich in this way, without working, and acquired many antiques.
