What you're saying isnt answering anything.
"Chinese good in Math (advantage) but they also lazy (disadvantage)."
This is racist and ignorant. And God isnt either.
Do lazy people build the "Great Wall of China"?
"Japanese are hard-working (advantage) but they hold too much pride (disadvantage)"
What's wrong with having pride? How many japanese people do you personally know to determine this conclusion?
"Europeans? They are willing to learn (advantage) but they have to disadvantage - they are too materialistics"
There are materialistic people through out the world. Even some indian people are materialistic.
Think before you type, these flaws are inherit in humans and seen throughout the world. And steriotyping people is ignorant and shows stupidity.
