GANGUE, or CANG  , the European name for the Chinese Kia or Kea, a portable pillory, carried by offenders convicted of petty offences . It ccnsists of a square wooden collar weighing from 20 to 6o lb, through a hole in which the victim's head is thrust . It fits tight to the neck and must be worn day and night for the period ordered . The offender is left exposed in the street . Over the parts by which it fastens slips of paper bearing the mandarin's seal are pasted so that no one can liberate the condemned . The length of the punishment is usually from a fortnight to a month . As the cangue is 3 to 4 ft. across the convict is unable to feed himself or to lie down, and thus, unless fed by friends or passers-by, often starves to death . As in the English pillory, the name of the man and the nature of his offence are inscribed on the cangue .
