假如你是Li Ming，你收到你的外国朋友的一封咨询信：
Dear Li Ming,
For the coming winter vacation(寒假), my family and I want to spend our vacation in a place for seven days. We would like to go somewhere in China not only warm but also interesting.We don’t mind how far we have to go. It has to be a place where we can swim every day,and it would be nice if our hotel is not
expensive but clean and comfortable.We like to pay no more than $6000 for the trip . Could you please
give us your suggestions (建议)for vacation sports(景点)?
Thanks a lot.
Yours,
Robert
