Is Durban, South Africa safe?

The public security situation in Durban is poor and the crime rate is high. The main forms of crime are holding a knife, robbing property, vehicles, violence, rape and so on. It is suggested that I go to Durban to enhance citizens' awareness of self-prevention and pay attention to the following matters:

(1) Try to go together and not act alone;

(2) valuables, gem ornaments and brand-name clothing should be properly kept, and some ornaments should not be exposed;

(3) Avoid entering or leaving specific residential areas and deserted streets and places;

(4) Go out as little as possible before sunrise and after sunset;
