Where is a good place to take photos of couples in Changchun?

I know a very good restaurant near South Lake. I forget the name of the entrance to the South Lake swimming area, but I will pass by every time I go to South Lake. Students are filming there, and I can go to the nearby South Lake, which is very convenient. The specific location is at the intersection of Gongnong Road and Angang West Road, or you can see it by taking 3 15 to Nanhu Swimming Area.
