Origin Story
话说古代有个小镇，镇上有个老木匠，他手艺精湛，做的木椅结实耐用，深受百姓喜爱。起初，老木匠做的木椅很受追捧，每天都有人来订购，但是几年后，镇上其他木匠也学会了做这种木椅，一时间，街上到处都是这种木椅，老木匠做的木椅虽然质量好，但已不再稀奇。这时，老木匠才发现，他以前引以为傲的技艺，如今已经屡见不鲜了。
Once upon a time, there was a small town, and in this town lived an old carpenter known for his superb craftsmanship. His sturdy and durable wooden chairs were highly sought after. At first, the carpenter's chairs were very popular, with orders coming in daily. However, a few years later, other carpenters in the town learned how to make the same chairs. In no time, these chairs were everywhere. Though the old carpenter’s chairs remained high quality, they were no longer unique. The old carpenter realized that his once-prized skill had become commonplace.
