In my opinion, It is nothing but a sort of communication in English. the most difficult problem you may meet is that you are the passive one to anwser what the interviewer ask you. Moreover, a increasingly large number of partcipants is being stunning in China. You can give it a try to imagine that how it is horrible for those interviewers to meet so many persons and then get always and almost the same answer. Therefore, I think personally that you should express something you own, unique and special.
