Chou Collection, Upper Volume Radical: Enclosure (wéi) Yi Kangxi stroke count: 16 Page 221, Entry 11 Pronounced yi (falling tone). Shuowen Jiezi (Explanation of Graphs and Analysis of Characters) states it means to move in a circuitous manner. It cites the Lost Book of Zhou (Yizhoushu): The clouds rising in a trailing, intermittent manner, half-visible and half-hidden. Xu Kai says: In the Great Plan (Hongfan), the five types of divination mention rain, clearing, mist, gathering clouds, and auspiciousness. The term yi represents the appearance of vapors trailing off in a continuous, unbroken line. To be half-visible and half-hidden corresponds to the saying in the Records of the Grand Historian, Treatise on Turtle and Yarrow Divination (Shigui ce zhuan): whether it rains or does not rain, whether it clears or does not clear, the vapors are not joined together. In the Modern Text Book of Documents (Shangshu), it is written in a variant form (yi).
