”King Jian Dispelling the Drought”, Volume Four of the Chu Bamboo Slips Collected by the Shanghai Museum, was a very interesting piece, which most scholars have thought to be about the ritual hosted by King Jian to dispel the drought. In this paper, we point out that the first half of this volume was mostly about how King Jian got sick under the drought, what kinds of divinations were required to relieve him of the disease, and how the king and his liegemen argued about the reduction of the decorum. It's not until the second half of the volume that the drought was described.
