William Alexander,
The costume of China, illustrated in forty-eight coloured engravings
(1805)
“ The Mandarin is seen attended by soldiers and servants, who are bringing his dinner; the double umbrella, or ensign of his authority, is conspicuously placed to demand respect; the flag and board at the stern, with Chinese characters on them, exhibit his rank and employment; these insignia of power also serve as a signal for other vessels to make clear passage for him, in consequence of which, such boats are seldom obstructed in their progress through the immense number of vessels constantly employed on the canals. ”
