That’s a very generous interpretation. I don’t know mandarin but these are likely a transfer of grammar constructs from the primary language to english, in the same way the Dutch will say “make a picture” or “the house of my parents”, which can be justly classified as awkward rather than as linguistic flair.

If someone was editing my writing, it would feel a bit patronizing if they said grammar mistakes (many of which come from my mother tongue Portuguese) are “adding flair”, as they are not a stylistic choice.
