The mainland immigrated to Hong Kong, and there was a fifth-grade child who didn't know much English. What kind of primary school is better? It is best to have a detailed address and overview!

I suggest you go to Su Ze Primary School.

It is the only school in Hong Kong that uses Mandarin as the teaching language.

But its courses are unified with those of other schools in Hong Kong. You can look up relevant information online.

I just came to Hong Kong when I was a child, and I went to school there without knowing Cantonese. Later, I learned. As for English, I can take my time. English in primary schools in Hong Kong is relatively more difficult than that in the Mainland. It might be a little harder. If not, you can consider making up lessons in Hong Kong.
