Origin Story
从前，在一个小山村里，住着两位老农，一位姓张，一位姓李。张老汉家擅长种植水稻，而李老汉家擅长种植果树。一年，张老汉家的水稻收成不好，而李老汉家的果树却获得了丰收。张老汉便去李老汉家寻求帮助，李老汉慷慨地送给了张老汉一些果子。来年，李老汉家的果树收成不好，而张老汉家的水稻却获得了丰收，于是张老汉又送给了李老汉一些稻米。就这样，两位老农互相帮助，互通有无，一直生活得很幸福。他们的故事在村里传为佳话，大家都称赞他们之间“有来有往”的友谊。
Once upon a time, in a small mountain village, there lived two old farmers, one surnamed Zhang and the other surnamed Li. Old Zhang's family was good at growing rice, while Old Li's family was good at growing fruit trees. One year, Old Zhang's rice harvest was poor, but Old Li's fruit trees had a bumper harvest. Old Zhang went to Old Li's house for help, and Old Li generously gave Old Zhang some fruit. The following year, Old Li's fruit trees had a poor harvest, but Old Zhang's rice had a bumper harvest, so Old Zhang gave Old Li some rice. In this way, the two old farmers helped each other, exchanged their products, and lived happily ever after. Their story was told in the village, and everyone praised their "give-and-take" friendship.
