Well, if we are speaking about the context of our country, there's a stigma in learning English, which I think its not wise. Learning Mandarin does help, but once a lot of these children get into university, they will realize that not learning English would be a huge mistake as people who know it, automatically does better.

It's not because they are smarter but all the books are in English, Google is in English (Translation is not accurate) and the exams are in English. So although many people won't want to admit it, learning it does help.

Aside from English, your mandarin is really good too. It has been 10 years since I last wrote in Mandarin..haha
