I think the very simple and correct expressions you can use as the followings: Forget it!/skip it!/I don’t wanna talk about this any more.

Dont speak with someone in superfluous words.Cauz it will be silly and make no sense at all.

I think maybe the subtle difference between the 2 words is as the follows: If you have an image of something or someone, you have a picture or idea of them in your mind. Your impression of a person or thing is what you think they are like, usually after having seen or heard them.

The first one and the last one was a little bit incorrect in grammar.I think you should choose the second one.The second one is right.))

The above questions you asked about can be translated literally with their own phonetic alphabets behind as follows: Hello.= 你好！ni hao Good evening.= 晚上好！ wan shang hao Good morning.= 早上好！zao shang hao What is your name?= 你叫什么名字？ni jiao shen me ming zi Where do you live?= 你住在哪里？ni zhu zai na li Thank you.= 谢谢。xie xie
