4. The three knives
Wáng Róng dreamt that two knives,
and then a third knife, were nailed into the roof beam.
Master Li Yì explained to him:
"The character dao: knife, repeated three times gives the character zhou
(chief of) province, so you will enter the Prefecture".
Soon after that, he became Governor of a province.
As Wáng Róng had, without doubt, plotted to become governor,
the "Damocles knife " was only in appearance hanging over his head
(though the goodwill of the emperor is always a two-edged sword,
as suggested by the first part of the dream).
