Venus (金星: the Great White, the essence of metal; its colour is white; its nature is courage; it is the emblem of the general; it circles the heavens once in one year, visible for 244 days; when it first appears in the west at dusk, its motion is somewhat swift, moving one degree and a small half per day; slowing down gradually, at 249 degrees it remains stationary for eight days, moves retrograde for ten days, stays hidden at dusk for twelve days, and then becomes visible in the east at dawn; generally, in eight years it completes five cycles, appearing five times at dusk and five times at dawn).
