how to I make my child understand even after trying everything she's still screams the whole day

A. So start ignoring the child for the timing is the child is screaming this you should just ignore the child and tell your child you scream and shout I’m not going to listen to you keep screaming and shouting one time when you stop paying attention to the child the child will understand that this is not working and the child will stop in the meanwhile you will have to keep telling to the child that if you want something if there’s something we can talk politely there’s no need to shout and scream because if you do so I’m not responding
