history
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.
