In the literary works such as "Ujishui Monogatari" (Tales of Ujishui), in the era of Emperor Saga, there was graffiti written by Takamura which said, 'Everything will be fine if there is no evil,' which could be read in a couple of different ways. Nonetheless, however, it could be interpreted as saying, 'It would be better if Emperor Saga did not exist.'
『宇治拾遺物語』などには、嵯峨天皇のころ、「無悪善」という落書きを「悪（さが（嵯峨のこと））無くば、善けん」（「悪なからば善からん」とも読める。いずれにせよ、「嵯峨天皇がいなければ良いのに」の意。）と読んだ。
