Besides, it' s better to go to a place with a lake or river and hills covered with trees in the area. ZHANG HUA: I like this idea. （4） . LIU HUI: And they can either walk around the lake or take a boat for relaxation. ZHANG HUA: （5） . LIU HUI: Exactly. Thank you for your suggestions, I will work out an itinerary for the trip this afternoon. ZHANG HUA: You' re welcome.
