Why didn’t the woman want to go to Changzhou?

W: David, we have been working very hard during this year. Don’t you think we need a nice holiday?
M: Of course. But I am wondering where we should go. Let’s make a plan together.
W: Great! But it’s really hard to decide.
M: What do you think of the following cities? Changzhou, Suzhou and Yangzhou.
W: I went to Changzhou two years ago, which left a very bad impression for me. Some citizens were not polite, although the hotel service was OK.
M: Alright, forget Changzhou. How about Suzhou and Yangzhou?
W: To tell the truth, I have never been to these two cities, but my parents have been to, they said it was really a good trip, especially the food there was very tasty.
M: OK, now let’s try to call the travel agency to make sure of some details of our travel.
W: Oh, I think we’d better not go with the travel agency; the timetable of the team will make it not easy to enjoy the travel, and sometimes the guide is not very considerate.
M: You are right. I really hate to go to a scenery packed with people. But if we book air tickets and make hotel reservation ourselves, we cannot get any discount, especially in this peak season.
W: I have a good friend who is working in a travel agency, maybe she can help us.
M: Great! I can’t wait for the travel. Suzhou and Yangzhou, so beautiful places!
W: I will call my friend now, and tell you the details later.
M: OK, bye-bye!
