In my personal idea, this is just senseless conclusion and tests. We can not judge human's talent and gift just by some tests, anyone has some potential talent just need to discover by someways. Our nationality has realized our adv and disadv about education, we have been imporving and making it better to catch up the global advanced technology, to let our children adapt to the global trend. Compared with US students, china students just good at examples, may get higher scores ... etc, while US students are very good at "imaging, doing, trying" ... Please don't forget that China is a farm country. Also, 2usd equals to 14RMB, that is not bad life for a low cost level countryside.
