《宋史·志·卷三》
日月五星经由天衢，那么天下和平；经由阳道，那么有旱灾、丧事；经由阴道，那么有水灾、战争。
七曜由乎天衢，则天下和平，由阳道，则旱、丧；由阴道，则水、兵。
If the Sun, Moon and Five Planets pass through Tian Qu, then the world will be peaceful; if they pass through Yang Dao, then there will be drought and mourning; if they pass through Yin Dao, then there will be flood and war.
