The list is biased towards the west.

Western chinese cuisine vastly differs from the local chinese food or at least what people in my area would eat in their daily lives.
You say that the food here is mainly oily and spicy, but there are so many Chinese dishes that are steamed, so no oil is even used. And we eat vegetables like no others.

Dishes like general tso chicken, sweet and sour pork are more western than Chinese. I have never tried general tso chicken.
Sichuan cuisine, where most spicy dishes originate from, are decent in popularity in my area but it is something people would eat once or twice in a month.
