A: Is someone helping you, Ma'am?
B: No. Actually, I'm looking for a sweater as a present for my mother. But I’m not certain what kind I should want. 
A: oh. Let me see. What about this style? It’s the fashion now. 
B: well, it’s a bit too loud（招摇）. I think my mother would prefer something plain and quiet. Do you have something different from this one? 
A: ok, what about that one?
B: The style is fine, but this pink is too bright for my mother. It’ll be ok if it’s a shade lighter.
A: Mmm-hmm. It is a very bright pink. Well, we have some more colors. How about the light blue one?
B: ok, I think that color maybe suits my mother’s complexion（肤色） . Doesn’t it fade?
A: Of course not. ?It wears well and keeps its shape. 
B: How much does it cost?
A: 200 Yuan.
B: The shirt is nice, but I suppose it’s too expensive. Can you cut the price a bit? 
A: Ok. We will offer you a special discount of five percent. That’s our rock bottom price（最低价）. You will find it is of good quality and well worth the money. 
B: ok. I’ll take it.
A: By the way, what size does your mother wear?
B: Medium. 
A: Yes. Just a moment, please.
B: That’s wonderful. Here is the money.
