Caviare, Filleted Anchovies and Anchovy Paste were advertised in the North China Daily News in 1914 only. This  suggests that ordinary Chinese consumers did not eat such products, for two main reasons: first, they were considered as luxury products that only a few Chinese elite could afford; second, according to Carl Crow's observations, the Chinese diet was mostly vegeterian, essentially for religious reasons (influence of buddhist doctrine). As such luxury foodstuff tended to disappear even in the North China Daily News after 1914, we may asume that both newspapers - and beyond, both Chinese and foreign markets - engaged in a democratizing process of consumption in the 1920s.
