《史记·七十列传·汲郑列传》
每逢五天一次的休假日，他经常在长安四郊置备马匹，骑着马去看望各位老友，邀请拜谢宾朋，夜以继日通宵达旦，还总是担心有所疏漏。
每五日洗沐，常置驿马安诸郊，存诸故人，请谢宾客，夜以继日，至其明旦，常恐不遍。
Every five days when the holiday came, he often prepared horses in the four outskirts of Chang'an, rode his horse to visit his old friends, invited and showed gratitude to his guests, and would continue through the night and day without end. He was always worried that he would miss someone.
