I feel that not teaching in the mother tongue will have an impact on the effectiveness of education. Teaching the Chinese language subject in Putonghua is also closely linked to the communization of Hong Kong. It will eventually endanger the position of Hong Kong Cantonese.
我覺得非母語教學會影響教學效能，普教中同香港赤化亦有密切嘅關係，收屘會危害本地粵語嘅地位。
