hi,
i have tried speaking to him in mandarin and so has my dad, but he refused to acknowledge us. He understands what we said , sometimes he will nod or shake his head, but he refused to answer us or he will do so in english. When i bought him chinese books, he threw them aside and told me not to buy chinese books again cos he will not read or do them....sigh.....i think if i send him to classes, he will hate me even more hahaha...but where do they conduct classes that will encourage them to like chinese?
