I've started dating American girl in Guangzhou,China. Where shall I take her in weekend nearby Guangzhou?

I am new to China. I've started dating an American girl in Guangzhou, China. She asked me to take her somewhere in the weekend to have a romantic dating. Where shall I take her? Suggest me some nice places near Guangzhou except HK, Macau, Shenzhen. If I start love-making in a car/theatre/park here, will cops bother? Plz excuse if the ques is bad
