Beijing,Shanghai, Jiangsu, and Zhejiang scored the highest in the 2018 PISA, followed by Singapore, Macao, and Hong Kong. Taiwan is quite a few notches down.
More info here:
It is very interesting to note the ranks among all Chinese groups. Mainland (BSJZ) ranks the highest. Singapore the second. Macao the third. HK the fourth. TW is the lowest.
Then, look at the closeness to the US, politically, culturally, economically, and socially, mainland is the farthest, Macao the second. Singapore the third. HK the fourth. And TW is the closest.
What conclusion can we draw from these observation? I think I have enough evidence to conclude "
The more you learn from the US, the stupider your offspring are."
Down the road a few years later,
Taiwanese will be the lowest class Chinese in intellectual capacity and in education.
HKers will be the second lowest class Chinese in intellectual capacity and in education.
Macanese, Singaporean and main-landers will be more or less the same class in intellectual capacity and in education.
What kind jobs Taiwanese and HKers are going to have in the future?
Are they going to be the designated janitors, dish-washers and servants of the Chinese society? Sure. No one will hire morons. And those who are proved intellectually deficient in PISA Tests are going to have hard times in find jobs in Chinese society.
