He is only 10, hard (too early) to tell. He has a bit of talent. -
Yet I have seen other "really talented" juniors that have developed
a "complete" game at age 10 (or 11). - Some of those are
"home-schooling" and plays tennis 3-4 hours every day.

While he plays about 3-4 times a week, 1-2hours each time. And he
plays piano too (a typical "chinese" approach :-)). Of course, we
told him, study is always the No.1 priority.....

So there is no comparison.

I got your email addr. Yes, in the future, I would like to ask you
for some expert advices.
