//Create a trigger on contact object with before insert and before update event.
trigger ContactTrigger on Contact(before insert, before update){

//Create list of account id and query on Account obejct with details you need and then add then you can use below code
for(Conatct c : trigger.new){
 for(Account aa: queriedAccountList){
   if(c.AccountId == aa.Id){
   c.MailingCity = aa.MailingCity;
    }
}
}
}
