Deletion of Cantonese wedding

Comment: not exactly a duplicate, more like a regional sub-topic. The main question is whether the sub-topic has been noted in  as being sufficiently different from its parent topic to the extent that it deserves its own article. This differs by topic; Cantonese cuisine and Cantonese (linguistics) are obviously notable as subdivisions of Chinese cuisine and Chinese language, to give two examples at one extreme; at the other extreme, there's non-notable regional subtopics like "Cantonese American", which was redirected to Chinese American as the result of Wikipedia:Articles for deletion/Cantonese American|this AfD discussion. I'll do some reading over the weekend and see what I can come up with in the way of sources
