2018年，有香港網民留意到香港教育局小學中文網上教學資源頁面度，宋欣橋寫嘅文章《淺論香港普通話教育的性質與發展》強調，「香港漢族人的母語是漢語」，粵語只屬「地域變體」。呢篇文章再次引起普教中嘅爭議。香港大學中文教育研究中心總監謝錫金撰文反駁。
In 2018, some Hong Kong netizens noticed that in the Hong Kong Education Bureau's primary school Chinese online teaching resource page, Song Xinqiao's article "On the Nature and Development of Putonghua Education in Hong Kong" emphasized that "the mother tongue of Hong Kong Han people is Chinese", and Cantonese is only a "regional variant". This article once again caused controversy in the general religion. Xie Xijin, director of the Centre for Chinese Education at the University of Hong Kong, wrote a counter-argument.
