máo zhǔ xí de nà ge jīng diǎn xiē hòu yǔ “ hé shàng dǎ sǎn , wú fǎ wú tiān ”
that classic double pun used by Chairman Mao, "A bald monk holding up an umbrella, no (respect for) law and order." (法 (fǎ, “law”) and 髮/发 (fà, “hair”) are homophones in Chinese; 天 (tiān) literally means sky, but it is also short for 天理 (tiānlǐ, “heavenly justice”).)
