Ming dynasty portrait of officials wearing wushamao（烏紗帽）and robes with mandarin squares
Futou (富头), also known as the wushamao (乌萨穆), is the headwear of Ming dynasty officials, consisting of a black helmet with two wing-like flaps of thin, oval shaped boards on each side. According to the Da Ming Hui Dian (大明會典), ordinary citizens are not allowed to wear this headdress unless attending events involving any noble families/officials. In modern China, wushamao is commonly used as a metaphor for officials and government posts.
