Alright, I understand what you mean. The more words you ask with the word 'FEI' in it, the better. These words usually describe things or people that are very good, outstanding, or special. For example, the present is not the same as the past (jīng fījiābèi) -It means that things or people have changed compared to the past. They are very good, outstanding, or special. Unusual (fāi téng tíx) -It refers to things or people that are very outstanding and special.
