Yes, I have seen Hefei (as well as other cities in Anhui) and fully agree with you that i'd rather stay in Zhejiang.

However, my wife is from Anhui and we made a deal (it's all about compromise, i think?) that we'd move closer to her home, family, friends, etc. one day. Several years later i'm quickly running out of excuses as to why we should stay in Zhejiang.
