Do you still have old photos of Huai 'an in the 1990s?
I remember, but there were no digital cameras at that time. When you take pictures with a camera, you use film. You have to pay for the movie. Taking a photo is not as easy as it is now. If you accidentally waste one, you can remember what it was like. There is no picture. Maybe you can find that kind of memory when you go to a place where there is no demolition. Don't forget to take out your mobile phone and click it.
