Primary 2 needs a tuition?

I would recommend to get them attend language classes. It's very important to be bilingual and there is no better time to start now because they have to start young ~ Kids also learn new language faster! Personally, I was raised speaking two languages but I found that it's more challenging to get the kids to do that in current environment. You can consider sending them to Le Xue Education if you're looking to improve your child's Mandarin. Their tutors are experienced and passionate.
