Yi: change
6 versions. The old pictures at left show the sun with its rays emerging from behind a cloud. On OB often used to indicate change of weather. The Yi-sacrifice is a sacrifice to the sun. Yi-ri (change-day): good fortune of the sun (appearing after absence, thanks to an ancestor or spirit).
In Northern China weather was unpredictable: long droughts, sudden torrents. Too much rain was life-threatening: the Yellow River might cause a flood.

Zhen: trial (ask oracle). Zhen is a ding, a sacrificial vessel (1) with the sign bu for ‘divination’: crack in scapula or tortoise-carapace (2). Oracle-consulting, but also receiving an answer. And the obligation to follow the advice of the gods: so it is also perseverance and correctness. Sometimes the Yi says “not permit determination”: don’t ask advice, find out every moment anew what this moment asks for.
