F: Thank you. The tea smells good. What is it called? ,M: It's called Tie Guanyin, and is a kind of Wulong tea. ,F: I've heard this name before, but I could never understand the tea classification. ,M: It's confusing and there is no agreement on it. Generally speaking, there are 4 kinds of tea based on processing methods. They're green tea, black tea, Wulong tea and scented tea. ,F: It is said that different kinds of tea have different health benefits, isn't it? ,M: Yes, it is.

However, pregnant women should not drink it. ,F: There seems to be a lot to know about tea. You must tell me more about tea culture in the future. ,M: Sure, I'll be glad to.
