In 1645, regent Dorgon enforced the
剃发令 'queue order' on conquered Han populations under the slogan
留头不留发，
留发不留头 ('keep your head and lose your hair, or keep your hair and lose your head'). Refusal triggered the Jiading Massacres
嘉定三屠. The queue remained mandatory until the 1911 Xinhai Revolution, when cutting it became a symbol of severing ties with the dynasty.
