How to add rates based on cities and distrects

Hello, i want to add new cities and new districts for those cities but adding rates for those cities and districts for example :

Libya is the one country i ship to so it’s chosen by default
after that i want the user to select which city he is located in Libya for example :

Tripoli shipping cost is defined by the district within it for example :
Tripoli -> nofleen = 10$
Tripoli -> alSaraj = 15$

another city example :

Benghazi -> all districts = 30$

and so on
is there any method to do this.
