And the Ch'ing dynasty Empress Dowager Tsu-his (1835-1908) once banned opera performers from singing the line "when the sheep goes into the tiger's mouth it won't come out again" from the opera Lu Tang Chun--naturally because she was born in the Year of the Sheep.
清代慈禧太后更曾禁止戲子唱「玉堂春」中的「羊入虎口有去無還」，自然是因為她屬羊。
