those kids are just groomed from toddler age
ofcourse studying and learning is great but this is not the way
Yup.
I dated a Vietnamese girl many years ago.
Her nephews were like this. One of them could play some of Beethoven's work on the piano with his eyes closed. And complete a rubix cube in less than 3 minutes.
He was 9 years old.
Won the regional spelling bee 4 years in a row. Had nearly perfect grades.
It wasn't because he was smart, it was because his parents forced him to practice these things 12 hours a day, 7 days a week.
When he got home from school, he did his homework immediately, ate dinner and then studied for the NEXT grade year for 2 hours.
It was insane and he hated everything about it, but had no choice.
If he didn't get straight A's or win whatever competition he was forced into, his parents threatened to kick him out of the house to live on the street.
