Children reply only in Mandarin, while Cantonese resources are hard to find

In a restaurant, parents ask a question in Cantonese, but their primary-school child answers only in Mandarin — until the parents simply switch to Mandarin to accommodate them. Local parents say schools mostly teach in Mandarin, and with mainstream online videos, games and entertainment almost entirely Mandarin-dominated, children get nowhere near enough Cantonese exposure day to day — even everyday terms like riding a bicycle are now said the northern way.

Even at traditional elite schools, some parents notice their children speak only Mandarin. Yet parents who want to deliberately preserve their mother tongue for their children have no clear way in: quality Cantonese teaching materials and audio-visual content aimed at children are relatively scarce, the share of Cantonese options in online videos is overwhelmingly small, and parents struggle to sustain such demand on their own — the market lacks a systematic supply of Cantonese learning and entertainment resources for children.
