I may be wrong, but "litchi" might be incorrectly spelled. If I'm correct then it should be spelled "lychee". It's a fruit native to Asia. Here's a picture:
And "Raison" is a South Korean cigarette brand:
And "Ome" or "Ume" is a native fruit of Japan, or at least called by that in Japan. Here's a picture of the fruit:
As for "Migua", if it's a literal translation from Mandarin, it should mean "Honey Dew" or some similar kind of melon fruit.
"Zaozai" also if literally translated, it should mean a vegetable type of fruit. Hard to describe, it's mostly used in Asian remedies. Sort of like a miniature tomato(but smaller) and has a unique tea like flavor. Some Chinese chefs use it to make broth for Chicken soup.
I'm assuming that since the liquids are manufactured in China, they are geared towards an Asian audience, thus the creation of these flavors. I know for a fact that lychee can easily be obtained in any Asian supermarket, so theoretically you could buy(if they are in season) some and try them out to see how you like the flavor.
Hope this helps. I've yet to try any of these flavors. Just ordered a batch recently from Eastmalls.net, they should be arriving soon.
Btw, I'm curious what your source for these liquids. Some of them are actually quite appealing to me. I don't see some "Migua","Yunyan" or "Ome" listed on Eastmalls. Nevermind, I just noticed them. Apparently some of them aren't available as part of the "Custom Sampler Special". I also noticed that the images also reflected the items. Guess having the images posted here doesn't really help much.
