Rustling of Leaves

 Rustling of Leaves  was an air shūji which taught that the best rumors were the ones with no obvious perpetrator, and that for gossip to take root, it must seem to come from everywhere at once. The courtier cleverly placed hints for people to find, setting up conversations that would lead to the rumor spreading without their action, or even using false letters or impersonation to draw new people into the spreading story.
