If you want a better public security, the house should be clean and new. This requirement is only for the community, so it is not cheap. The best way is to share the community at least above 1100, depending on where you are better. If you are in the community around 2000, the supporting things are also better. Let&;s make do with it. Come out to study. You can rent a bad place in public security for about 500. Be careful there. It is almost the same. You can&;t be harmful. You can&;t be clean.
