What's your impression of Hefei?

My impression of Hefei is "civilization". When I first went to Hefei, because I was going to a place, smartphones were not popular at that time, so I could not find them by navigation. At that time, I asked a local resident on the way, and as a result, they patiently and politely told me how to get to my destination. At that moment, I thought Hefei was a "civilized" city, and now the development of Hefei is getting better and better. I heard there are many.
