Just to digress a little.
I have a player who comes once a year. He emigrated to the US but comes back once a year during winter for holiday. He lives in Chinatown, NY. He said the TT scene in Chinatown is pretty much dominated by people of East Asian origin, specifically Chinese ( no brainer here ). Their standard are pretty diverse, from very good to pretty low level. His level is pretty above average when compared to my club average but his level is pretty low skill when he meets those academic trained player from China ( e.g. students )
It is no brainier of the 10s of thousands of kids that learn TT "professional" from elementary school level in China.
Then you have 31 provincials/regions in China, say each of them has 5 sports school that feeds into the provincial team for U11 level.
Each school has 30 boys and 30 girls. That is near 10000 kids that are now "upgraded" from normal school tt, to sport school tt.
And then only 20 to 30 per gender goes into the provincial team - that is say another 2000 kids per age group.
By the time they stay in sport school / provincial junior team till age 16 and are in the 1st half of ranking, they are good enough to become national ranked in many tierd 2 or 3 TT countries.
however, only 20 per gender will end up going into the national team (cnt b team aka national junior team).
So what do you do with the other 1900 kids per age year?
Some will stay on and play full time, some will end up coaching later on, some will leave China and seek opportunities overseas in TT and some will leave the sport and 10 or 20 years later, be that uncle on the street that can beat any one.
The amount of sport school trained kids up till age 16 is plenty. Up to 18, then they are really good.
I have a friend, she left China age 16, was in the Chongqing junior girls team and moved to South Africa.
She only restarted playing at university. (3 years of no TT). So she got a bat, put SP on her BH (she is a 2 wing inverted), and her first year, she made SA womens champion, and QF in Africa. This is with no training, and literately just started 1 month before the tournament, amid a busy university schedule.
She stopped playing again at post grad, to focus on studies. There was no money for her in TT and olympics wasn't a real target for her, otherwise, she would easily have gone to 2 olympics or more.
