（Peter, a student from the UK studying in Xi'an, meets his mom at the airport in the morning. ）
Son: Hi, mom. I miss you so much.
Mom: . You've been in Xi'an for one year. How is it going?
Son: Pretty good. People here are very friendly, and there are many places of interest. This afternoon, let's visit the Bell Tower first.
Mom: ?
Son: It is called the Bell Tower because there is a big bell in the tower. It was used to tell time in the past.
Mom: That's interesting. It's like Big Ben in our country. ?
Son: No, it's not far. It's just 10 minutes' walk from the hotel.
Mom: That's good.
（In the evening, they take a walk near Dayan Pagoda. ）
Mom: Wow, the night view here is amazing.
Son: Yes, mom. Look, Dayan Pagoda! It was built over 1,300 years ago and it's well-protected.
Mom: Unbelievable! Such a long time! ?
Son: They are poems, written on lights.
Mom: That's cool. Xi'an is rich in history and culture. Can you show me around other places?
Son: . We can also go to many other beautiful places in Shaanxi. They are worth visiting.
Mom: Great. I'm sure I will have a wonderful time.
