Everyone has different preferences, so it's hard to tell the whole story.
As far as I'm concerned, at home, I usually cook noodles or porridge (Zhanjiang porridge is not Guangzhou porridge).
If I eat out, there are many more choices, but if I'm not in a hurry, Zhanjiang people usually sit down and have breakfast. People around me often eat nothing more than rice congee fried dough-strips soybean milk and powdered rice rolls milk. Rib rice. And I think people around me don't particularly like eating a certain kind of breakfast, but they can buy it. They all go to a nearby breakfast shop and order whatever they suddenly want.
At noon, they eat the most.
