Since you are using the word "shifted" i'm guessing you are local. I'm not picking on you, but rather it's an important distinction with regard to ability to gain entry into good local schools. If your concern is learning Chinese, then local schools are the way to go.
International Schools do not teach Chinese intensively in the way local schools do, except perhaps at the new Chinese
International School on Dunearn. For local schools, everyone knows that Nanyang is the leader in Chinese language, but the school is exceptionally difficult to gain entry to.
