Which city have you been to that disappointed you?

I have been to Wuxi, and I had a good impression of Wuxi at first, but once when I passed a park and a hotel, the security there was particularly fierce, and it seemed that I was quarreling with people. He left a hotel before passing by, and then the security guard shouted three times to go away when he was still standing far away. The next day, I passed a park in Chong'an Temple, and I may have strayed into a place. The security guard came and pulled me and said let me go. I was about to leave when the security guard said, "If I let you go, you still won't go." I was so depressed that it took me a long time to recover. So I haven't been to Wuxi since then.
