hong
Synonym discussion
Sense: noun/1
All three words describe historical commercial operations, but 'hong' is the most specific. 'Factory' (from Latin 'factorium', a factor's establishment) was used across the British Empire for overseas trading stations — it focuses on the physical premises and the factor (agent) who ran them. 'Trading house' and 'merchant house' are broader terms that can describe any era or region. Neither carries the licensed-agent role specific to the Canton System. A scholar writing about 19th-century Chinese trade would use 'hong' for precision; 'trading house' would be the clearer choice for readers unfamiliar with the term.

Etymology
Borrowed from Cantonese 行 (hong4), meaning 'trade, firm, business'. The Cantonese term itself comes from Chinese 行 (háng), which originally meant 'row' or 'line' and later acquired the sense of 'shop, trading establishment'. European merchants in Canton adopted the word in the 18th century and brought it into English.
