To manage a city well, the most important thing is sanitation, good appearance and high quality of citizens. First, we must create a "sanitary city"; "Garden city" is a variety of trees. In this regard, first of all, it is stipulated that the rate of new urban green space is not less than 35%, and the rate of old urban green space transformation is not less than 25%. At the same time, some places with insufficient greening should be replanted.

There are many indicators about "civilized cities". Fan Huaping believes that the starting point should be to improve people's civilized quality, and the government should also improve work efficiency. Finally, a city should not only be clean and convenient for people's lives, but also be guaranteed by safety. In order to create a "safe city", Qujing City has made great efforts to improve from various aspects such as civil air defense, joint defense and seasonal defense.
