不仅庭院的规模能反映主人身份、地位的高低，宅门也能体现这种等级观念。宅门可以分为王府大门、官宅的广亮大门和金柱大门、南方来京官员和商人家的蛮子门、寻常百姓家的如意门以及更低档的墙垣式门等。除此之外，还包括门上的门簪、门钹、门扇上的对联等。

Not only the scale of quadrangles could reflect the owner’s dignity and social status, the house gate also displayed the obsession of hierarchy. The house gate included the gate of prince’s mansions and gracious golden gates of official residences, the Manzi Gates of officials from southern and merchants, Ruyi Gates and the simple wall gates of ordinary citizens, etc. Besides, the house gates also included the decorative cylinder on the gate, cymbal-shaped article with a knocker, and couplets on doors.
