Oh, the standard at American Chinese restaurants. This kind is supposed to be the lightest in flavor and the "summer" tea. Summer tea, meaning that, if you drink it in the summer, it will cool you down (not quite sure how that works, but okay).
Okay, so it is what it sounds like. They literally pick flowers (often chrysanthemums), dry them, and put them into hot water. It's actually quite good. Flower tea is a Springtime tea (makes sense), and it's also supposed to be good for women. I didn't ask why.
Another American Chinese restaurant tea standard, this one is the Winter tea. It's supposed to have the highest caffeine content (though I don't think that most kinds are equal to a typical Starbucks drink). This kind's kind of bitter, and not exactly my fave.
This is (you guessed it!) supposed to be the Fall tea. I actually only have had this a couple times. I would liken it to Lipton's with a little bit of fresh soil mixed in. While that may sound a little gross, it's actually quite good.
So, that's my tea roundup. Of course, there are many other kinds of teas in China. Next time you go out for Chinese food, enjoy the tea!
