Origin Story
从前，有个秀才赶考，路遇暴风雨。他躲进一间破庙，庙里已有几个人。其中一人衣着华丽，自称是朝廷官员，另一人衣衫褴褛，却自称是布衣。暴风雨过后，官员要走，秀才犹豫要不要送他。这时，衣衫褴褛的人说：‘大人是朝廷命官，走时我等自当护送。’秀才听后，立刻明白了，便也跟着众人一起送别官员。官员走后，衣衫褴褛的人哈哈大笑，秀才不解，那人解释道：‘这叫见风使舵，你以后要多留心。’秀才恍然大悟。
Once upon a time, a scholar was traveling to take an exam when he encountered a violent storm. He took shelter in a dilapidated temple where several other people were already present. One was richly dressed and claimed to be a court official, while another was in rags and introduced himself as a commoner. After the storm subsided, the official prepared to leave, and the scholar hesitated whether to see him off. At that moment, the man in rags spoke up, "A high-ranking court official surely deserves an escort." The scholar understood instantly and joined the others in seeing off the official. After the official's departure, the man in rags broke into laughter. The scholar, perplexed, asked for an explanation. "That, my friend," replied the man, "is called adapting to the situation. You should pay more attention in the future." The scholar finally understood.
