Nanjing is a place suitable for couples to play.

Personally, I suggest Xuanwu Lake and Lovers Garden. The reason is: Xuanwu Lake has a good scenery, so you can go boating, see the scenery, bring your own food, and you'd better not buy the contents and souvenirs. Confucius Temple is very cheap. The Lovers Garden is very interesting. There are some things about Chinese and Western weddings, such as wedding stones, churches, carriages, wedding cars, etc. Many people take wedding photos, and there are many sunflowers that can be barbecued. However, I suggest that you go there when the weather is warmer. It's too cold now.
