The school had done such a fabulous job that he was pretty good in Hanyu Pin Yin. He was able to read Chinese books out loud too.
However, there was one aspect which I forgot.
Despite being able to read and write Chinese, his conversational Chinese was hesitant and unconfident.
I was very surprised. What a major blind spot it was.
Now we had to work on that. It was not as natural as we had limited vocabulary in our daily conversation but we all tried our best.
