Conclusion

Promotion:

By spontaneous efforts for the use of Hong Kong Cantonese in public spaces. The more prevalent it becomes, the less likely that the variety is going to be marginalised.

Preservation:

To align one's identity, be it social or political, with the use of language. If we are facing the pressure to adopt another variety, we are obliged to be conscious of it, or even resistant.

How should we preserve and promote Hong Kong Cantonese?
