Excellent points, DJ.
(BTW) I am 2 decades ahead of you. 40 is the new thirty and my elder daughter is 40 and doesn't look a day over 30.)
This is a summary of an American trying to understand how to peel the hyperbole off Chinese sales pitches and even understand why they use it in their business dealings.
The way Chinese Restaurants name themselves with hyperbole-Golden Dragon, Flowers of the Moon, Golden Phoenix, refer to Chinese mythical conventions. They are part of Chinese culture where most people understand the mythical references underlying the words. Often the restaurants have flowery descriptions as an intro to their menus.
The fact that pearls, gems,any commodity, may have flowery descriptions on paper, in speech, or on the net, leads me to believe that hyperbole is a Chinese cultural/business convention. If the numerous novels and Chinese documentaries on TV are any indication, it has always has been a literary style culturally Chinese businessmen or diplomats know how to use.
Admittedly, I am no expert on Chinese culture, these are opinions I have developed by buying pearls and eating in American Chinese restaurants, reading novels and watching tv. You can make fun of me for my acquisition of these ideas, (but some of the tv was PBS!
) I imagine other American buyers having had similar exposure to mine, have taken similar positions on this style of prose too. However, most Americans would not try to understand the hyperbole, they either fall for it or refuse to buy it and both of them end up feeling bad about it and believe the Chinese are crooks.
My conclusion is that until Chinese merchants understand America's cultural style and adapt to it, like giving accurate sizes in pearl shopping, overinflated descriptions, will be rampant. Americans need to translate Chinese-style hyperbole already in English, to unexaggerated English. For instance take a size off any pearls you wish to buy, to more accurately reflect their size on a caliper. It is perfectly legal to do this in China as they have decided by law what 7mm means. (7mm includes pearls down to 6.1mm or something close to that. And only 1,3,or5, will be 7mm pearls) We have other translations of flowery prose in threads on the forum.
