Go to Xi 'an to play in a few days.

In this case, you can reply as follows:

1. That sounds great. Xi is a very attractive city. What scenic spots are you going to visit?

2.Xi 'an, I've always wanted to go there. Be sure to go when you have the chance! Are there any recommended foods and games?

3. How many days later? That's good. It's just that I'm free these days Why don't we go to play together after you come?

4.Xi an? Well, I also happen to have the idea of traveling recently. Can we team up together?

It's a good thing to visit Xi 'an, but it's getting cold recently. Remember to put on more clothes.
