节奏文明，楚文明，楚简，清华简，司岁

《司岁》出自《清华大学藏战国竹简》第十辑，是战国楚系文献中关于时间制度最完整的篇章。它以“岁”为核心，记录岁首行令、祭祀节序与政务节拍，展示楚国如何以天象、节令与行政相互对应，建立自有的时间管理系统。在楚人的思想中，时间不是流逝，而是循环：星辰运转，节气递更，政令复始。这是楚文明的“时间算法”——当时间被立法，文明开始自我运转。Si Sui, included in the tenth volume of the Tsinghua University Collection of Warring States Bamboo Slips, is the most systematic Chu-state text on temporal governance. Centered on the concept of “sui” (the year), it records royal decrees, sacrificial schedules, and administrative rhythms that align politics with the heavens and seasons. For the Chu people, time was not linear but cyclic—the stars moved, the rites returned, and order renewed itself. This was the time algorithm of Chu civilization: once time became law, the world began to operate on its own rhythm.
