#Person2#: I'm fine, Katherine. I just stayed up late last night working on my Chinese.
#Person1#: Oh, poor you. You know what? I found a new way to learn Chinese and it works very well.
#Person2#: You did? Do tell me. I've spent all these months trying to learn something new about it, but I've made little progress!
#Person1#: Sure. I'm learning Chinese through songs.
#Person2#: So you're learning Chinese songs?
#Person1#: You can say that. I can actually sing some of them now.
#Person2#: That's a real achievement. How did you do that?
#Person1#: I start by listening to the song a few times and after several times I am able to follow the singer.
#Person2#: It makes sense.
#Person1#: It does. I've learned some Chinese folk songs this way. They are clearly presented and easy to follow.
#Person2#: Can Join you, Katherine? I do want to have a try.
#Person1#: Why not? I downloaded a beautiful song the other day. We can learn it together now.

#Person1#: Yes, just in case we run into me new characters.
#Person2#: Ok. I will bring it with me.
