Origin Story
从前，有两个村庄，分别以种植水稻和棉花为主。每年收成时节，村长都会组织村民进行庆丰收活动。第一个村庄的水稻收成很好，村长便决定举办一场盛大的宴会，席间有各种美味佳肴和美酒。而第二个村庄的棉花收成一般，村长考虑到村民的实际情况，决定组织一场简单的庆祝活动，大家一起分享自制的点心和茶水。两个村庄的庆丰收方式虽然不同，但这都是根据各自村民的实际情况作出的安排，体现了“因人而异”的智慧。 后来，邻近的村庄也来取经，他们看到第一个村庄的盛大宴会，纷纷效仿，结果却因资源不足导致后续生活困难。而第二个村庄则因其务实的做法，生活越过越好。 这个故事告诉我们，处理事情不能千篇一律，要根据具体情况，因人而异，才能达到最佳效果。
Once upon a time, there were two villages, one primarily growing rice and the other cotton. Every year at harvest time, the village heads would organize harvest festivals. The first village had a good rice harvest, so the village head decided to hold a grand banquet with various delicacies and fine wine. The second village had an average cotton harvest, so the village head, considering the villagers' circumstances, decided to organize a simple celebration where everyone shared homemade snacks and tea. Although the harvest festivals in the two villages differed, both arrangements were based on the specific situations of their villagers, reflecting the wisdom of "yin ren er yi".
