HongKong education problem

I think the main problem for hkep is to follow which standard.Before we are using englands one but now we return back to china, we now use chinas one.However, i dont know why we dont change the system earlier instead of 10 years and more later.But i think it would be fine after the system is changed.
for the solution, i hope china government can assign or exchange with the offical in hk.Therefore they can share the ideas.Since we found that students in china are very strong in calculation and science. I think the method used in china may help in hk also
