在古代中国的历史长河中，有许多关于诚信与友谊的感人故事流传至今。其中，“范式守信”的故事尤为著名，它不仅体现了古人对诚信的重视，也展现了朋友之间深厚的情谊。

原文：

昔者，张劭与范式同窗读书。二人情同手足，相交甚笃。后张劭归乡，范式留京继续学业。临别之际，张劭设宴送别，并与范式约定两年后的重阳节，范式将至张家拜访。范式欣然应允。

时光飞逝，转眼已至约定之日。张劭父母见范式未至，心中忧虑。张劭安慰父母道：“范兄为人诚信可靠，必会如期而至。”果然，当日下午，范式风尘仆仆赶到张家，果真履行了两年前的承诺。张劭一家大喜过望，设宴款待范式，席间欢声笑语不断。

Once upon a time, Zhang Shou and Fan Shi were classmates studying together. They were as close as brothers and shared a deep friendship. After Zhang Shou returned home, Fan Shi stayed in the capital to continue his studies. At their farewell banquet, Zhang Shou proposed that two years later on Double Ninth Festival, Fan Shi would visit his family. Fan Shi readily agreed.

Time passed quickly, and soon it was the day of their appointment. Zhang Shou's parents grew worried when Fan Shi did not arrive. Zhang Shou reassured them, saying, "My friend Fan is honest and trustworthy; he will definitely come as promised." As expected, in the afternoon, Fan Shi appeared at Zhang Shou's house, fulfilling the commitment made two years earlier. Zhang Shou's family was overjoyed and held a banquet to welcome him, filled with laughter and joy throughout the evening.

这个故事告诉我们，无论距离多远、时间多久，只要坚守承诺，就能赢得他人的信任与尊重。同时，这也提醒我们，在现代社会中，诚信依然是维系人际关系的重要纽带。让我们从古人的智慧中汲取力量，将诚信融入日常生活，让这个世界变得更加美好和谐。
