在中国古代的历史长河中，有许多关于诚信的故事流传至今，其中“范式守信”便是其中一个广为传颂的经典案例。这个故事不仅展现了古人对诚信的重视，也传递了人与人之间应坚守承诺的重要性。

原文

昔有一范姓书生，居于乡野，性情淳厚，笃行仁义。其友张劭，亦一才子，二人同窗数载，情谊甚笃。一日，张劭谓范生曰：“吾欲往京师求学，然家贫无资，恐难成行。君若能助我一臂之力，则吾必铭记于心。”范生闻言，慷慨允诺，曰：“君之志向可嘉，吾当竭力相助。他日君学有所成，务须归来践约。”

张劭感激不尽，遂赴京师求学。时光荏苒，岁月如梭，转眼两年过去。范生每日耕读，不忘与张劭昔日之约。某夜，梦中忽见张劭来告：“三年后，当归乡与君相会。”范生惊醒，深信此乃天意，遂将此事告知家人，并约定以鸡黍为宴，以待故人归来。

三年之后，果真如期而至。张劭果然从京师归来，范生设宴款待，二人欢聚甚欢。自此，二人友谊更加深厚，世人皆称其为“鸡黍之交”。

Once upon a time, there was a scholar named Fan who lived in the countryside. He was kind-hearted and devoted to moral principles. His friend Zhang Shao was also a talented scholar, and they studied together for several years, forming a deep friendship. One day, Zhang Shao said to Fan: "I wish to go to the capital to further my studies, but I am poor and lack funds, making it difficult for me to proceed. If you can help me, I will always remember your kindness." Hearing this, Fan generously promised: "Your ambition is commendable; I will do all I can to assist you. When you succeed in your studies, be sure to return and fulfill our agreement."

Zhang Shao was deeply grateful and left for the capital to pursue his education. Time passed quickly, and two years went by. Fan continued to farm and study diligently, never forgetting his promise to Zhang Shao. One night, he dreamed that Zhang Shao came to tell him: "In three years, I will return home to meet with you." Upon waking, Fan believed this to be divine guidance and shared this dream with his family, arranging a banquet of chicken and rice to welcome his old friend.

Three years later, just as predicted, Zhang Shao indeed returned from the capital. Fan hosted a feast to celebrate their reunion, and their friendship grew even stronger. People called them the "Chicken and Rice Friendship."

这篇故事虽然简短，却蕴含着深刻的哲理：诚信不仅是个人品德的重要组成部分，更是维系人际关系的纽带。无论时代如何变迁，这种精神始终值得我们传承和发扬。
