Are there some methods to help me to differentiate which sentence is more rich and bright colours? If two or three sentences express the same meaning, I really want to know which one is more rich and bright colours.Please forgive me I can't give you some examples beacause of my poor english.I know this question is hard to answer. Maybe you can give me some examples. Thank you very much.

what's the differences between "mandarin" and "Chinese"? why so many foreigners translate "汉语" into "Mandarin" ? In China, we translate "汉语"into "Chinese".And we even don't know the word "mandarin"at all.Is "mandarin" more common than "Chinese"? what's the differences between "mandarin" and "Chinese"?
