I think if we want true relations then villages or rural areas are best to find sincere people as people of villages are very simple and mostly they don't focus on giving harm to anyone but when we live in urban area then we have people of our level and they always wants to harm you for the sake of their personal benefits but this not happens every time and I am just giving a generalised idea that in which area people are more simple and sincere but over all there is a mixture of people live in different areas.

Good luck to you for your efforts you made.
