The competition has been there for a long time. I personally know some people who have won the regional champion. They are as boring as other non-perfect English speakers. To some of them, this is just a way to get themselves into a good university. It's no use to speak English, or frankly speaking, any foreign language well if one does not know how to think and what to express. It's the content that matters. Yitang Zhang doesn't speak perfect English but when he speaks, people would listen. I think what Chinese students really need is logic and philosophy.
